Once again, The Economist hits the nail on the head with a write-up of the now infamous "cash for clunkers" program:
Rebate schemes like this tend to encourage buyers to advance purchases that they would have made anyway, thus cannibalising future sales. The termination of a car-scrappage scheme in France in the 1990s led to sales plunging by 20%. Nor is it certain that the scheme provides a more general boost to the economy, as buyers may have been put off other purchases in order to afford a new vehicle.The American economy is an incredibly complicated machine. When the government decides to stick its greasy hands inside and fiddle around with the parts, bad things tend to happen. This isn't to say that government policy can't have positive effects -- but in almost every case, it comes at a price. Short-sighted policies that promise too-good-to-be-true benefits lose their shine when the consequences come a-knockin' on the public's door.
...
The green benefits are also hotly contested. The scheme should help to make America’s car fleet slightly less fuel inefficient, but there are significant environmental costs in scrapping perfectly good cars and building new ones.
Right now, members of congress are considering a piece of legislation that would transform America's massive healthcare industry. The benefits are obvious: everyone gets healthcare coverage. But before trigger-happy reformers vote aye, they might want to dwell on the unintended consequences of their pet project. Yes, just about every modern country provides universal healthcare coverage. But a lot of those countries have to deal with huge doses of taxation, high levels of sustained unemployment, and a stagnant work force.
After considering the pros and cons, a lot of people may still support the legislation. The good of universal coverage may outweigh the associated evils.
But there are some things that no one can foresee. Our economy is based on billions of unpredictable transactions between individuals. If seemingly harmless programs like "cash for clunkers" can create unintended ripples in this economic ocean, what could happen when the government gives one of our largest industries an extreme makeover?
I'm really not sure. But you can bet it won't be all unicorns and rainbows.
