Last week, the US extended its 'cash for clunkers' programme. It calls for destroying car engines. So, mechanics pour sodium silicate into the crankcases. "It just don't make sense," said a used-car-parts salesman in Dayton, Ohio. This week, we open up the hood and take a better look. Does it really make sense, we ask? In answer, we guffaw. Then we invite dead economists to guffaw with us.
Richard von Stigl, among others, pointed out in 1923 that there is a big gap between real economics and the vulgar economics that drives policy decisions. On the one hand, serious observers study what happens in a pure, natural economy and draw their truths from its crystal streams. On the other, the meddlers distort the economic world so much that the observations of the old economists hardly matter. Downstream from the meddlers' camp, the water is not even fit to drink. In theory, as well as in fact, the planners never know what they are doing: "The ... knowledge of the circumstances of which we must make use never exists in concentrated or integrated form," began Friedrich Hayek in 1945, "but solely as the dispersed bits of incomplete and frequently contradictory knowledge which all the separate individuals possess."
A 'good' is a good only insofar as it is good to the person who wants it. The public servant as able and self-less as he may be has to guess. History and theory tell us what happens; he usually guesses wrong. Only the individual knows what he wants and how to get it. He compares one good against others using prices to guide him to where he gets the most good for his money. But when the government steps in with its subsidies, it effectively dams the flow of price information. Now, the consumer, with no clean signal to guide him, makes mistakes. He may be lured to buy a new car. The central planners may be pleased. They see the effect they desired more auto sales. But what don't they see? We invite Frederic Bastiat for an opinion (1850):

"Between a good and a bad economist this constitutes the whole difference the one takes account of the visible effect; the other takes account both of the effects which are seen, and also of those which it is necessary to foresee. Now this difference is enormous, for it almost always happens that when the immediate consequence is favourable, the ultimate consequences are fatal, and the converse."

But who listens to Bastiat or Hayek? Ten countries have taken up 'cash for clunkers' programmes. In Britain the government puts up £2,000 to grease the deal... with a total of £300 million earmarked for the programme. In France, buyers get e1,000 toward the purchase of a new car. Everywhere, the programme is hailed as a success it is widely thought not only to boost auto sales, but to help revive the economy, reduce pollution, cut oil imports and even lower highway deaths. We haven't heard that buying a new car contributes to weight loss, but we haven't read the papers this morning. Even 'free market capitalists' such as Larry Kudlow say they like it:
"The cash-for-clunkers rebate programme is working. ... And the price tag of the program is a mere $2 billion compared with the trillions of dollars Washington has been wasting. So, for once in our lives, Washington spending is giving us a good bang for the buck."
Bastiat knew better. He described a scene where a careless boy had broken a shop window. The store's owner was annoyed, until a foolish economist pointed out that the broken window was a blessing in disguise. It gave work to the glaziers and glass makers. The glaziers then could buy other things and thus did the whole economy enjoy a bounty from this single act of vandalism. But wait; Bastiat wanted to know: if you could improve the lot of mankind by breaking windows, why not smash every window in Paris? And if you could improve the lot of mankind circa 2009 by destroying cars, why not crush them all? And planes. And trains. Heck, destroy everything. Think of the boom that would accompany the rebuilding!
Obviously, it doesn't work that way. Replacing broken windows, or cars, takes resources away from some other uses. Lured by phony price information, buyers send phony signals to the rest of the economy. The automakers produce more cars. Steel, which might have gone to refrigerators, is used for car doors. Oil, which might have been used to generate electricity, is used to stamp out fenders. Savings, that might have been invested in new industries, go to prop up an old one.
Kudlow allows himself a peek at the unseen consequences: " yes, it's quite possible that government rebates today will steal car sales from next year. But let's cross that bridge next year..." Then, he even wonders, briefly, at the obvious foolishness of it... almost as though he were a serious thinker: 'Well, why not just spend another $100 billion and give consumers checks for everything?' Or, 'Why not spend another trillion?' Well, I don't want to go there..."
No one wants to go there. Real economists and used auto parts dealers shake their heads: 'it doesn't make sense,' they say. But who gives a damn?
