Public spending 1

... if you cut today's public spending by the IPPR's other figure of 3.8%
this year and every year for the next 25 years,
it would fall to £263.8 billion,
which is still higher in real terms than it was in 1970-71.
It's a long time ago, certainly,
but we weren't exactly running around in nothing but woad 40 years ago,
there's plenty of room for 3.8% cuts. ...

----------  o  O  o ----------

There is currently a certain amount of debate in the UK about public spending. Iain Duncan Smith wants to "make work pay". Frank Field argues that means-testing rots people's souls. Support for the benefits system, a report says, is at its lowest level for three decades. And according to Alegra Stratton, the political editor of BBC TV's Newsnight, the government is eyeing an end to the link between benefits and inflation.

Ms Stratton laid out the options for public spending over the next few years, please see Wednesday's edition of Newsnight between 15'38" and 21'28". If the budget is to be balanced, the Institute for Public Policy Research say that public spending will have to be cut by 3.8%. If the NHS, education and international aid budgets are to be ring-fenced then the other departments face a cut of 8% in their budgets. There will have to be cuts, says Ms Stratton, and cuts upon cuts, and what does "8% cuts elsewhere, beyond the fence" mean? It means 8%, that's what it means, but Ms Stratton assists her viewers' understanding by explaining that that's equivalent to:

BBC TV Newsnight 19 September 2012
Either that, or huge cuts in welfare, which brings us back to Iain Duncan Smith.

The debate isn't exclusive to the UK. Mitt Romney makes his own pertinent contributions to it in the US.

And it's not a new debate, as Polly Toynbee reminds us in the Guardian. "David Cameron's mission was to break the postwar consensus on the welfare state that survived Margaret Thatcher", she says, and quotes the Institute for Fiscal Studies (IFS) claim that the overall spending cuts planned by the coalition government are "almost without historical and international precedent".

(Notice that "almost". What the IFS mean is that there are historical and geographical precedents. Almost the opposite of what it sounds as though they're saying.)

The debate is over-heated at the moment, permanently in danger of taking off into outer space – Ms Stratton's Newsnight package, for example, uses Mozart's Requiem as background music. The debate needs to be tethered to planet Earth. It needs some facts, to ground it, and HM Treasury have kindly published those facts in their report Public Spending Statistics July 2012, which includes the figures below in Table 4.1 on p.42:

There follows a series of questions. DMossEsq doesn't know the answers.

41 years ago, 1971-72, annual public spending in the UK was £25.2 billion. Taking account of inflation in the intervening period, that is equivalent to £255.4 billion today in real terms.

Public spending today isn't £255.4 billion, it hasn't been maintained at its 1971-72 level. Instead, it's gone up to £694.9 billion. Why?

If public spending today was £255.4 billion, it wouldn't have been cut at all. For 40 years, it would have been maintained, guarded, ring fenced, ...

If you cut today's public spending by the IPPR's figure of 8%, it would fall from £694.9 billion to £639.3 billion, roughly the level of 2007-08. We were not in a state then – Ms Stratton please note – equivalent to having 70,000 fewer defence personnel and 20,000 fewer policemen and we wouldn't be now.

If you cut today's public spending by the IPPR's other figure of 3.8% this year and every year for the next 25 years, it would fall to £263.8 billion, which is still higher in real terms than it was in 1970-71. It's a long time ago, certainly, but we weren't exactly running around in nothing but woad 40 years ago, there's plenty of room for 3.8% cuts.

But was public spending in 1970-71 at the right level? What is the "the right level"? Perhaps we should choose a different base line. Which? And why?

Public spending today has gone up in real terms since the treasury's 1970-71 base line by a factor of 2.7208, it's increased by 172.08%. That means the state has taken on new burdens, burdens which it didn't used to shoulder. Is that a good thing? Or a bad thing? Is the state taking on unwonted responsibilities? Is it being intrusive? Is there any limit to the state's responsibilities?

The coalition government has not yet managed to cut public spending. Public spending has levelled off for two years but it hasn't been cut. Not appreciably.

It's hard to cut. It takes time.

Equally, it's hard to make material increases in public spending. Every time the NHS budget is materially increased, under whichever government, the question arises whether its systems can absorb all the extra money. Of course they can, but the question is whether the money can be used efficiently, without waste. No, it can't. Increases have to be planned, just as much as reductions.

The IFS describe 3.8% spending cuts as "unprecedented". For a conservative organisation like them, that is a criticism, they assume that you shouldn't do things that are unprecedented. If an action is unprecedented, does that mean it shouldn't be taken? Or is now the time to be radical?

The 172.08% increase from £255.4 billion to £694.9 billion over 40 years works out at a steady rate of increase of 2.5% p.a. But the change hasn't been steady.

Spot the cuts?

Cuts are not unprecedented. There are six years when public spending was cut:
  • 1977-78 (-3.9%),
  • 1985-86 (-1.1%),
  • 1988-89 (-2.3%),
  • 1996-97 (-1.6%),
  • 2000-01 (-0.9%)
  • and 2011-12 (-1.6%)
and 34 years when it went up.

There were two hefty increases in public spending, in:
  • 1973-74 (+10.6%)
  • and 1974-75 (+9.6%)
and the biggest ever was in:
  • 2001-02 (+11.8%)
followed by an unprecedented run of further increases – +5.6% in 2002-03, +5.8%, +5.0%, +4.0%, +2.2%, +3.4%, +5.2% and +4.8% in 2009-10.

To put it another way, public spending in 2009-10 (£705.6 billion) was 59% up on the 2000-01 figure (£443.7 billion) 10 years before:

Unprecedented?

Yes.

For 30 years, public spending had increased at an annual average rate of 1.9% from £255.4 billion to £443.7 billion in 2000-01. Then the rate of increase nearly trebled to 5.3% p.a., taking public spending in 10 years from £443.7 billion to £705.6 billion in 2009-10.

The end points of the solid lines in the graph above show what did happen, with the trajectory in between smoothed out. The dotted lines show what could have happened instead. On the established trend, the long run 30-year rate, public spending in 2009-10 could have been "only" £526.7 billion. Instead, it was £178.9 billion higher at £705.6 billion.

By the IFS's reckoning, those increases should not have been made.

Somebody nevertheless, ignoring the IFS, put their foot on the accelerator. During Labour's 1997-2001 administration, Gordon Brown as Chancellor of the Exchequer was wedded to Prudence. Thereafter, Prudence left and Mr Brown was joined by Sir-Gus-now-Lord O'Donnell, first as Permanent Secretary at the Treasury and then as Cabinet Secretary. Whose foot was on the accelerator? The cautious/prudent/indecisive and some say cowardly Brown's? Or O'Donnell's, the man to whom every government economist reported, the man who would be King?

Is the state better at allocating resources than individuals and private sector organisations? Or worse? Is state spending always benign? Clearly O'Donnell thinks the answer is "yes", but is it?

Today's public spending represents 45.5% of GDP according to the Treasury. With public spending standing at £694.9 billion, it follows that GDP must be £1,527.3 billion.

Does that mean that we can afford a public spending level of £694.9 billion, or that we can't? Is 45.5% of GDP the "right level" for public spending?

What's public spending got to do with GDP anyway? Does public spending act as a drag on growth? Or does it actually promote growth?

Can anyone answer these questions? Politicians? Mandarins? Economists? Journalists? You?

The Government Digital Service, no time to fit in Universal Credit, too busy

They're a ruthless lot, GDS.
They have to prioritise.
Millions of people could be given the opportunity to make work pay?
Too bad.
GDS have a website to write.

----------  o  O  o  ----------

At last the technical IT problems with Universal Credit (UC) are beginning to be reported in the national press, please see selected examples below.

UC is important. "Make work pay" means rescuing people from the poverty trap, where dependency rots their souls, as Frank Field puts it. And tragically, as Mr Field also puts it, "UC is on course for disaster".

There are political problems with UC. That is a matter for Parliament, and Parliament is debating it – the House of Commons Work and Pensions Committee is considering 500 pages of evidence from 70 organisations.

Suppose that Westminster resolves the political problems. Then what?

Then UC will still fail because of the IT problems introduced by Whitehall.

Digital by default
Whitehall has decided that all public services, including UC, should be "digital by default". That is, public services should be delivered over the web, and only over the web, please see newspaper articles quoted below. But something like ten million people in the UK have still never used the web. They will be "excluded by default".

Assisted digital
Whitehall has invented a phrase to plug the gap between the unwebbed and UC – "assisted digital". There will be an assisted digital programme, they say, to help their web novice parishioners to register with UC and to claim. There is no such programme, there is nothing more than the phrase and Whitehall's actual response, as opposed to their promised response, is simply not to answer the telephone, please see newspaper articles quoted below. That, Whitehall believes, will force people to use the web.

Identity assurance
Once forced onto the web, how do claimants prove that they are who they say they are? If they can't, either we risk denying benefits to people who are entitled to them or we risk automating benefit fraud. That invidious choice is currently avoided on the web by using the UK Government Gateway, which requires user IDs and passwords.

Whitehall believes that the Government Gateway is old-fashioned and too difficult for most people to use, and has promised to replace it with a new "identity assurance" service. Another phrase, another promise, another failure, please see newspaper articles quoted below, no use to UC, there is no new identity assurance service.

Cybersecurity
In their more lucid moments, Whitehall departments warn individuals, businesses and each other that the web is a dangerous place to be. Identity theft, industrial espionage, viruses, man-in-the-middle attacks, hacking, distributed-denial-of-service, you name it, it's a cyberthreat.

GCHQ has established an academic institute for cyberdefence. GCHQ appear to understand the problem. And yet simultaneously, schizophrenically, Whitehall has decided to put all public services including UC on the web, please see newspaper articles quoted below.

Cloud computing
"Cloud computing" is the solution, whatever the problem, according to Whitehall. Whitehall wants a G-Cloud – a government cloud – and they want to put all our data in the cloud where, they claim, it will be secure, it will be maintained in real time, always up to date and always accurate, cloud computing is flexible and cheap and efficient and trusted and always available (resilient, no down time, always safely backed up) and green and modern and fit for the 21st century.

Cockpoppy.

Not in this 21st century. Not on this planet.

Whitehall's G-Cloud team hosted a lively debate about the problems of cloud computing, pulled all the questions together and tried to crowd source some answers. They can't have liked the answers submitted and published only one – the limiting case of a crowd. The problems remain, unresolved, even the founder of Google is warning Whitehall against cloud computing, and yet G-Cloud proceeds, ensuring maximum risks to UC.

Agile
It is a sad fact that IT projects tend to come in late and over budget. Staggeringly late and eye-wateringly over budget. UC is meant to be different. UC is using "agile" systems development methods and "agile" means that systems are flexible, delivered on time and within the budget.

"Agile" is just another word. Computer Weekly magazine reported in June on an emergency project of the US military's:
... the effort is part of an emergency reform of IT projects using agile methods, on orders issued by the Department [of] Defense last year after 11 major computer systems went $6bn over budget and 31 years behind schedule.
Transformational government
UC is the victim of "transformational government", the overall Whitehall plan which incorporates "digital by default" and "assisted digital" and "identity assurance" and "cloud computing" and "agile". Iain Duncan Smith, the Secretary of State for Work and Pensions, looks utterly sincere in his desire to make work pay but he has failed. His officials have prevailed and undermined UC.

Steve Dover, for example, the director of major programmes at DWP and clearly a card-carrying member of the Transformational Government cult, worshiping computers and full of contempt for human beings, is quoted in the Guardian on the subject of UC as saying:
The starting point, I said to our telephony collaboration teams based in Newcastle, was just think of a contact centre, but it has got no people in it and think of an operating model that has got no back office, and start from there.
Francis Maude, the Cabinet Office Minister, is in charge of both cybersecurity (don't use the web) and the Government Digital Service (GDS, only use the web). How does he reconcile the two? On 31 October 2011, he announced that he was funding the nascent identity assurance industry with £10 million taken from ... the £650 million cybersecurity budget.

When it comes to IT, our politicians are apparently helpless in the hands of their officials.

Officials like Steve Dover, and ex-Guardian man Mike Bracken, the executive director of government digital services and Senior Responsible Officer Owner of the identity assurance programme. Bracken trundled Francis Maude off to Estonia to see what transformational government looks like in action. Before that, Mr Maude was made to go to California to listen to Google talking about the identity ecosystem. Later, there was a trip to Washington for Bracken's Government Digital Service (GDS) team.

Estonia, of course, precisely because the country's government has been transformed and relies entirely on cloud computing, was brought to its knees by the Russians in a matter of days in 2007. Why does ex-Guardian man Mike Bracken wish to expose the UK in general and UC in particular to the same vulnerability?

The trip to California included a talk given by Google on identity management. If the suggestion is that perhaps Google could provide the identity assurance that UC and other public services require, it should be understood what that implies. Application for benefits and the administration of their payment would become dependent on Google, whose name could conceivably one day replace Her Britannic Majesty's in our passports. As custodians of our identity, the company would tend to become part of the Constitution. Is Constitutional change in the remit of ex-Guardian man Mike Bracken?

The Washington boondoggle included a photo opportunity in the White House library, enough to turn anyone's head, and was the occasion for groupthink with GDS's transformational government opposite numbers working on NSTIC, the US National Strategy for Trusted Identities in Cyberspace. The fact that the US administration is pursuing the same mistaken strategy as the UK's does not alter the fact that it is mistaken.

GOV.UK
GDS's serious responsibilities are set out on its website under the following headings – assisted digital, digital engagement, directgov, ID assurance, innovation and single government domain. They concentrate on the single government domain task, producing GOV.UK, a re-write of all the departmental government websites that already exist.

No time to waste on UC
When GDS aren't visiting Estonia or the US, they're re-writing websites. They're not promoting digital engagement, they're not providing assisted digital services and DWP don't have the new identity assurance system that they need and that they were promised.

They're a ruthless lot, GDS. They have to prioritise. Millions of people could be given the opportunity to make work pay? Too bad. GDS have a website to write.



A selection of recent newspaper reports on the state of UC:

Last Saturday's Guardian, 15 September 2012, Welfare bill won't work, key advisers tell Iain Duncan Smith:
Seventy organisations wrote to the Commons work and pensions select committee last week, raising a host of potential objections to the universal credit, including doubts about the ability of the government to successfully deliver the IT necessary to unify benefit payments or use real-time wage information to ensure that work always pays better than welfare.

Those working with the vulnerable said the insistence that the system be wholly internet-based will leave many unable to access benefits, and claim the government does not have a plan B.
Next day's ObserverUnemployed deliberately held in call centre queues to promote website:
Jobseekers are being kept hanging on the telephone for at least five minutes before they are connected to a member of staff in jobcentres – a deliberate move to encourage people to make online claims, internal documents obtained by the Guardian reveal ...

Charities said that vulnerable people often do not have internet access ...

Underlining the new policy is the government's target that 80% of new claims for unemployment benefit should be made online by September 2013 ...

The problem for the welfare secretary, Iain Duncan Smith, is that the online flagship universal credit policy will only work if claimants not only claim jobseeker's allowance and other benefits online but also manage their benefits and job searches online ...

The Department for Work and Pensions emphasised that the government tried to ensure that poor people could access jobcentre call centres ...
Monday's Telegraph, Cyber attacks threaten welfare reforms, ministers warn:
Cyber-attacks by criminal gangs and hostile states are the biggest threat to the Coalition’s welfare reforms, ministers have said.

Iain Duncan Smith, the Work and Pensions Secretary, said he had sought advice from major internet retailers such as Amazon about how to keep his Universal Credit systems running, despite electronic sabotage and fraud.

Universal Credit is due to replace scores of individual benefits from next year, simplifying claims and allowing claimants to keep more of their benefits when they take paid work. The regime will be internet-based, with ministers intending that most claimants apply and report a change in circumstances online.

Appearing before a Commons inquiry into the reform, Lord Freud, the welfare reform minister, was asked what was the biggest risk to the programme. “I’ll say what the challenges are, what we need to get right: to get the security system working properly,” he said.

Private security companies will be commissioned to develop a system of “identity assurance” to check that only real claimants can get benefits. “That’s one of the biggest challenges,” said Lord Freud.

Mr Duncan Smith said: “There are states that wish to attack things, criminals that want to commit fraud.”

Unlike retailers, he said, the new system would have to keep running regardless of disruption: temporary interruptions of service would harm claimants. “We must always be ready for the moment we need to pay people the money,” he said.

The Government Digital Service, no time to fit in Universal Credit, too busy

They're a ruthless lot, GDS.

Universal Credit, ex-Guardian man Mike Bracken and Sir Jeremy Heywood

At last the technical problems with Universal Credit (UC) are beginning to be reported in the national press:
Universal Credit is due to replace scores of individual benefits from next year, simplifying claims and allowing claimants to keep more of their benefits when they take paid work. The regime will be internet-based, with ministers intending that most claimants apply and report a change in circumstances online.

Appearing before a Commons inquiry into the reform, Lord Freud, the welfare reform minister, was asked what was the biggest risk to the programme. “I’ll say what the challenges are, what we need to get right: to get the security system working properly,” he said.

Private security companies will be commissioned to develop a system of “identity assurance” to check that only real claimants can get benefits. “That’s one of the biggest challenges,” said Lord Freud.
Who's in charge of identity assurance? The Cabinet Office. More specifically, the Government Digital Service (GDS). Why is identity assurance one of Lord Freud's "biggest challenges"? Because there is no identity assurance available to UC or any other public service. Lots of talk. Lots of blogging. No identity assurance.

Ex-Guardian man Mike Bracken is the executive director of government digital services and Senior Responsible Officer Owner of the identity assurance programme. He flew Francis Maude, the Cabinet Office Minister, out to California to see the future:
Andrew Nash, Google’s Director of Identity, ran us through the current issues facing identity.He explained how Google aim to grow and be part of an ecosystem of identify providers, and encouraged the UK Government to play its part in a federated system. The UK ID Assurance team and Google agreed to work more closely to define our strategy – so look out for future announcements. Andrew also took the opportunity to walk the Minister through the Identity ecosystem.
He may have walked through the "Identity ecosystem" but ex-Guardian man Mike Bracken hasn't produced an identity assurance system that DWP can use for UC.

That job has been left to Vince Cable's Department for Business Innovation and Skills (BIS). The idea is to incubate a whole new market of trusted companies whose business it is to maintain Personal Data Stores (PDSs). We will each have a number of PDSs, according to BIS, and these will allow us to transact with government. PDSs will allow us to register for UC, for example, and for benefits to be paid computer-to-computer, with no messy human intervention adding "friction" to the system.

What companies? Who is going to maintain all these PDSs? BIS don't say. They don't say who and they don't say when. How long does it take to grow a mature identity assurance ecosystem from scratch? How long can UC wait?

UC faces any number of political problems. They may or may not be solved. Even if they are, UC will still be snookered by an unworkable IT system design. That design must have been agreed by Iain Duncan Smith's officials at DWP. They must have agreed to implement GDS's infantile science fiction ideas. And BIS must bravely have agreed to try to create a PDS industry overnight.

Obviously Iain Duncan Smith will get the blame for the failure of UC. And that failure will be a tragedy. The opportunity for people to escape the poverty trap will have been lost. If work can't be made to pay, says Frank Field, then the resulting state of dependency will rot people's souls.

But the failure is Whitehall's. N [please see comments below] And according to the Spectator, that failure is countenanced and even encouraged right from the top, by Sir Jeremy Heywood, Cabinet Secretary:
Sir Jeremy Heywood, the civil servant effectively running Britain, is letting it be known that he is ‘sceptical’ about Duncan Smith’s mission. This, in Whitehall, is the equivalent of a go-slow order. Civil servants will not waste time or personal capital on anything likely to join the identity cards and the NHS supercomputer in the graveyard of ministerial follies.

... [David Cameron] should throw his weight behind Duncan Smith rather than seeking to remove him. He ought to remind Sir Jeremy that, as head of the civil service, he is paid not to be ‘sceptical’ about government policy but to implement it. Welfare reform is the thorniest problem in government, which is why so many ministers have ignored it. It is far safer, politically, to leave the poor to rot.

Who's in charge of identity assurance? The Cabinet Office. More specifically, the Government Digital Service (GDS). Why is identity assurance one of Lord Freud's "biggest challenges"? Because there is no identity assurance available to UC or any other public service. Lots of talk. Lots of blogging. No identity assurance.
