Snappy comebacks to stupid questions: the eternal undeath of the credit-card analogy

How to respond when the prime minister says something simplistic and wrong.

One of the most pernicious simplifications in mainstream politics is the "credit card" analogy. You know the one: the British economy is like a maxed-out credit card, and we have a responsibility to pay it off.

It's pernicious because the British economy is nothing like a credit card, maxed-out or not. Britain has control of the very currency in which it owes debt; it can print money to pay bills. On top of that, its effect on the economy which is its revenue source is so large that if it scrimps and saves in order to pay down its debt, there's a very real chance its income will drop by even more.

But the analogy is unkillable, and even if politicians don't cite it directly, they apply its lessons nonetheless—as Cameron did last Thursday:

Labour’s central argument is exactly that. They say that by borrowing more they would miraculously end up borrowing less. Let me just say that again: they think borrowing more money would mean borrowing less. Yes, it really is as incredible as that.

He may not have said the magic words "credit card" (or similar analogies involving "household spending" or "Britain plc"), but the same implication is made: the national debt, and macroeconomics in general, is no more complex than a family budget.

That's not true. But the thing is, even if you apply the same analogy, Cameron's claim is still over-simplistic. Here are just some ways borrowing more money can mean borrowing less:

  • You are unemployed. You have great ability, but few qualifications. You take out a career development loan to pay for post-secondary education. You get a well-paid job as a result.
  • You are unemployed. You have ample qualifications, but no smart clothes. Before the first of a string of job interviews, you borrow enough to buy a suit, ensuring that you win gainful employment and don't have to borrow money to eat.
  • You live in a 1950s prefab. With no real protection against the elements, an uncomfortable proportion of your monthly income goes on heating. You borrow money to pay for insulation, your expenditures drop, and you use the extra to pay off credit-card bills.
  • Annual income six pounds; annual expenditure six pounds sixpence. Result: misery. You borrow some money to put solar panels on the south-facing roof of you Guernsey house, reducing your spending on electricity. Annual income six pounds; annual expenditure five pounds, nineteen shillings and sixpence. Result: happiness.

I could write some detailed sophistry about how each of those analogies apply to Britain. The first is broadly equivalent to "upskilling"; the second to spending money on promoting Britain overseas; the third to fixing our much-vaunted "crumbling infrastructure"; and the fourth to investing in the Green Economy.

But I won't. Because the way to discuss the macroeconomy isn't through trite analogies and dumbed-down explanations; it's through discussions of the macroeconomy. If you want the best discussion of whether Cameron's claims are true, I recommend you turn to Jonathan Portes' exhaustive examination, or Duncan Weldon's blow-by-blow account of the squabble between the PM and OBR. You won't find many comparisons to your own financial situation, but that just means you're getting the good stuff.

The rise of the green mayor – Sadiq Khan and the politics of clean energy

At an event at Tate Modern, Sadiq Khan pledged to clean up London's act.

On Thursday night, deep in the bowls of Tate Modern’s turbine hall, London Mayor Sadiq Khan renewed his promise to make the capital a world leader in clean energy and air. Yet his focus was as much on people as power plants – in particular, the need for local authorities to lead where central governments will not.

Khan was there to introduce the screening of a new documentary, From the Ashes, about the demise of the American coal industry. As he noted, Britain continues to battle against the legacy of fossil fuels: “In London today we burn very little coal but we are facing new air pollution challenges brought about for different reasons." 

At a time when the world's leaders are struggling to keep international agreements on climate change afloat, what can mayors do? Khan has pledged to buy only hybrid and zero-emissions buses from next year, and is working towards London becoming a zero carbon city.

Khan has, of course, also gained heroic status for being a bête noire of climate-change-denier-in-chief Donald Trump. On the US president's withdrawal from the Paris Agreement, Khan quipped: “If only he had withdrawn from Twitter.” He had more favourable things to say about the former mayor of New York and climate change activist Michael Bloomberg, who Khan said hailed from “the second greatest city in the world.”

Yet behind his humour was a serious point. Local authorities are having to pick up where both countries' central governments are leaving a void – in improving our air and supporting renewable technology and jobs. Most concerning of all, perhaps, is the way that interest groups representing business are slashing away at the regulations which protect public health, and claiming it as a virtue.

In the UK, documents leaked to Greenpeace’s energy desk show that a government-backed initiative considered proposals for reducing EU rules on fire-safety on the very day of the Grenfell Tower fire. The director of this Red Tape Initiative, Nick Tyrone, told the Guardian that these proposals were rejected. Yet government attempts to water down other EU regulations, such as the energy efficiency directive, still stand.

In America, this blame-game is even more highly charged. Republicans have sworn to replace what they describe as Obama’s “war on coal” with a war on regulation. “I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion, and to cancel job-killing regulations,” Trump announced in March. While he has vowed “to promote clean air and clear water,” he has almost simultaneously signed an order to unravel the Clean Water Rule.

This rhetoric is hurting the very people it claims to protect: miners. From the Ashes shows the many ways that the industry harms wider public health, from water contamination, to air pollution. It also makes a strong case that the American coal industry is in terminal decline, regardless of possibile interventions from government or carbon capture.

Charities like Bloomberg can only do so much to pick up the pieces. The foundation, which helped fund the film, now not only helps support job training programs in coal communities after the Trump administration pulled their funding, but in recent weeks it also promised $15m to UN efforts to tackle climate change – again to help cover Trump's withdrawal from Paris Agreement. “I'm a bit worried about how many cards we're going to have to keep adding to the end of the film”, joked Antha Williams, a Bloomberg representative at the screening, with gallows humour.

Hope also lies with local governments and mayors. The publication of the mayor’s own environment strategy is coming “soon”. Speaking in panel discussion after the film, his deputy mayor for environment and energy, Shirley Rodrigues, described the move to a cleaner future as "an inevitable transition".

Confronting the troubled legacies of our fossil fuel past will not be easy. "We have our own experiences here of our coal mining communities being devastated by the closure of their mines," said Khan. But clean air begins with clean politics; maintaining old ways at the price of health is not one any government must pay. 

'From The Ashes' will premiere on National Geograhpic in the United Kingdom at 9pm on Tuesday, June 27th.
