Dear Economist, My young son came home from school and asked me: “Mummy, what’s a credit crunch?” How can I explain this to a five-year-old? Ms LG, London Dear Ms LG, Once upon a time, there was a blameless girl called Consumerella, who didn’t have enough money to buy all the lovely things she wanted. She went to her Fairy Godmother, who called a man called Rumpelstiltskin who lived on Wall Street and claimed to be able to spin straw into gold. Rumpelstiltskin sent the Fairy Godmother the recipe for this magic spell. It was written in tiny, tiny writing, so she did not read it but hoped the Sorcerers’ Exchange Commission had checked it. The Fairy Godmother carried away armfuls of glistening straw-derivative at a bargain price. Emboldened by the deal, she lent Consumerella – who had a big party to go to – 125 per cent of the money she needed. Consumerella bought a bling-bedizened gown, a palace and a Mercedes – and spent the rest on champagne. The first payment was due at midnight. At midnight, Consumerella missed the first payment on her loan. (The result of overindulgence, although some blamed the pronouncements of the Toastmaster, a man called Peston.) Consumerella’s credit rating turned into a pumpkin and Rumpelstiltskin’s spell was broken. He and the Fairy Godmother discovered that their vaults were not full of gold, but ordinary straw. All seemed lost until Santa Claus and his helpers, men with implausible fairy-tale names such as Darling and Bernanke, began handing out presents. It was only in January that Consumerella’s credit card statement arrived and she discovered that Santa Claus had paid for the gifts by taking out a loan in her name. They all lived miserably ever after. The End.

Were an alien to pick up our news channels, it would conclude that human civilization depended on the production and purchase of cheap plastic rubbish. First came the concern that we might talk ourselves into not spending enough, then the fear that the banks wouldn't lend us the money to spend even if we wanted to. In November, our governments borrowed money and gave it to us in the hope that we'd catch on. Are we really so dependent on consumption? In the short run, yes. Economists worry about a sharp fall in consumer spending, because when demand for goods falls, so does demand for labor. Our desire to spend less is quickly revealed as a desire to spend less hiring each other (and our friends in China) to make things. Result: economic collapse, unemployment, misery. In the long run, the picture is completely different...
