First of all, the administration's claims that Cash for Clunkers will benefit the environment are complete rubbish. Sure, we'll be burning slightly fewer fossil fuels and cutting down on air pollution. But how could anyone consider this an environmentally-conscious initiative when every single one of the cars traded in is crushed into a cube and placed in a landfill? Assuming that each trade-in receives the full $4,500 rebate, and allowing part of the fund to go toward destroying the trade-ins, the $1 billion fund should allow for over 200,000 trades. That's 200,000 crushed-up cars in landfills that weren't there last month. And if Congress injects the proposed $2 billion addition to that plan—which they likely will—we can increase that number to 600,000 cars.
(As a side note, Cash for Clunkers is also a waste of thousands of perfectly good vehicles which could have been donated to those in need. Especially with unemployment rates as high as they are, having reliable transportation is essential to gaining employment. Still, the Cash for Clunkers initiative requires that trade-ins be crushed. What's more—it requires that they be in drivable condition before they're destroyed.)
But the Cash for Clunkers program is perhaps most flagrantly stupid when it comes to the economics of the situation. What it essentially comes down to is that the government is encouraging consumers to take on more debt. During a recession. (Isn't irresponsible borrowing what got us into this mess in the first place?) Because only new cars qualify for the rebate, every consumer who takes advantage of Cash for Clunkers loses 10-20% percent of the car's value as soon as they drive it off the lot. And if they don't use cash, which most of them won't, they'll come away with more debt than they had before the trade.
Even more disturbing is that those who buy new cars under Cash for Clunkers are not entirely responsible for that debt. The value of the rebate becomes more debt for American taxpayers, because, like most of what Barack Obama has accomplished so far, Cash for Clunkers is paid for with taxpayer money which the government does not have (meaning "has yet to collect").
My next criticism is that Cash for Clunkers interferes in the free market. The program artificially inflates demand, meaning that once it ends, demand will shrink to even less than what it would naturally be during a recession. The current, increased demand for new cars also hurts the used car business, and the destruction of the trade-in vehicles takes business away from the auto repair industry. The government is not just manipulating the "invisible hand." They've basically chopped it off.
I realize this is a long post. There is a lot to criticize about Cash for Clunkers. In short, though, it basically amounts to yet another bailout of the auto industry, this time in the form of yet another government handout. (Interestingly, this auto industry bailout is actually benefitting foreign automakers the most, since four of the top five cars purchased under the program are Japanese.)
But I guess we could look on the bright side. At least this bailout will get some Americans the new car smell, rather than a hundred-million-dollar bonus for some Citigroup executive.
