George Osborne’s claim that his nonsense policies have magically turned the economy around, coupled with his equally-preposterous claim that the UK needs another seven years of austerity before he can balance the books – provides a fine example of the duality at the heart of Conservative economic policy.

He needs to convince you that his choices have made a difference and the nation’s fortunes are changing, but he also need to convince you that we’re in a terrible mess – or he won’t have an excuse to continue cutting more public services and selling them into the private sector so his rich friends can use them to fleece you.

The two claims are not only contradictory of each other – they are self-contradictory. The evidence shows that Osborne’s policies delayed the recovery, rather than encouraging it, and the ‘Starve The Beast’ plan he cribbed from George W Bush has long been recognised as harmful to any country’s economic health; by cutting services he is starving the economy of the liquidity that is its lifeblood.

(This is a point worth remembering: Whenever a TV news reporter says Osborne or the government want to make cuts in order to “save” money, they mean the government will be “taking money out of the economy” – which will consequently be worth less. As a result, some people will have to become poorer. Can you guess who?)

Before we congratulate Osborne in ways that are anything like as effusive as David Cameron’s endorsement earlier this week, let’s look at the facts: According to Martin Wolf in the Financial Times, in three and a half years, the UK’s economic performance has improved by just 2.2 per cent – against a prediction of 8.2 per cent by his pet Office of Budget (Ir)Responsibility. In the second quarter of 2013, Gross Domestic Product was 3.3 per cent below its pre-crisis peak and 18 per cent below its 1980-2007 trend, making this the slowest British recovery on record.

Osborne and the Conservatives point proudly to the strong increase in private-sector jobs but, as Mr Wolf states, “this is hardly something to boast about”. While employment – on paper – is at an all-time high, productivity has fallen back to the level it reached in 2005. What does this say about the quality of the jobs that are being filled? Are they high-quality, long-term, well-paid careers, or are they part-time, zero-hours, throwaway fillers? We all know the answer to that. Average wages have been cut by nine per cent, in real terms, since 2010 – and they are still falling.

Even by the standards of other crisis-hit, high-income economies, the UK’s performance has been dismal, says Mr Wolf, pointing to work by Spencer Dale and James Talbot of the Bank of England. This indicates that the Eurozone has performed just as badly – but the difference is that the Eurozone countries do not have control of every economic lever that is available to them; Britain does.

Osborne claims that high global inflation and the performance of the Eurozone have impacted on the UK; Mr Wolf’s assertion is that austerity is the reason for this disappointment – and Osborne was just as much a cheerleader for austerity in Europe as he has been for it in the UK. Furthermore, as the Labour Party pointed out in its report, “David Cameron’s out of touch, you’re out of pocket” (2013), inflation in other G7 countries has been lower than in the UK, indicating that high global prices have little to do with the problem.

“Yes, but,” says Osborne, “austerity has kept interest rates down.” Did it? Did it really? In that case, interest rates would have been kept low because of the promise (in 2010) that borrowing would be brought down by 2015. When the Coalition came to power, Osborne said he expected to borrow a total of £322 billion by 2015. In March this year, that figure had risen to £564 billion – an increase of 75 per cent! Meanwhile the deadline for the national debt to start falling has slipped from 2014-15 back to 2017-18 and the level at which the debt was expected to hit its peak has jumped from 70.3 per cent of GDP to 85.6 per cent. The deficit has been stuck at £120 billion a year for the last two financial years, despite the repeated claims that it has been cut by one-third. None of this has affected long-term interest rates and neither did the loss of the UK’s AAA credit rating in February this year.

Here’s why – as explained in an article on this site in June:

As Professor Malcolm Sawyer notes in Fiscal Austerity: The ‘cure’ which makes the patient worse (Centre for Labour and Social Studies, May 2012), “It is well-known that a government can always service debt provided that it is denominated in its own currency. At the limit the UK government can ‘print the money’ in order to service the debt: this would not take form of literally ‘printing money’ but rather the Central Bank being a willing purchaser of government debt in exchange for money.” This is what is happening at the moment. Our debt is in UK pounds, and we can always service it. Our creditors know that, so they remain happy to continue financing it.

“With interest rates at the zero bound, austerity weakened the economy relative to what might otherwise have happened,” wrote Mr Wolf.

“Nobody thought recovery would never happen under austerity, merely that it would be damagingly delayed… This has been an unnecessarily protracted slump. It is good that recovery is here, though it is far too soon to tell its quality and durability. But this does not justify what remains a large unforced error.”

Looking to the future, Osborne has reacted to the new barrage of Labour policies, all of which have been carefully costed against savings in current budget areas, with a series of rushed measures that are entirely unfunded. Remember that, next time a Conservative accuses Labour of borrowing and spending!

The married couples’ allowance, worth less than £4 per week (and less than £2 if you’re on a low income) is unfunded. The promised fuel duty freeze is unfunded. These will cost more than £2 billion and no source has been identified.

And what about the £12 billion stage two of the housing ‘Help to Buy’ scheme, that Osborne rushed forward to this month?

He has pulled £14 billion out of nowhere, but still expects us to believe he will resume his stalled deficit cuts by £35 billion by 2015, £42 billion by 2017-18 and £43 billion by 2020, in order to create a budget surplus.

All the while, he is promising “improved living standards for this generation and the next”. For whom? These cuts must come from somewhere, and they mean removing a cumulative total of £120 billion from the economy each year by 2020. That has to come from somewhere.

Look at the amount by which bosses’ pay in FTSE100 companies has increased in the last three years – 32 per cent, while average worker pay has dropped by nine per cent.

Do you really think the “Have-yachts” will be paying for these cuts?
