The debate over the "Cash for Clunkers" program is interesting. It is a perfect microcosm of the debate over the entire economic progam of the Obama administration.
Those who favor the program argue that it stimulates the economy and is good for the environment. Those who oppose the program argue that is an example of the fallacy of the broken window and that it is not environmentally beneficial because while an old car only has the gas mileage environmental costs a new car has manufacture and gas mileage environmental costs.
The response from those who favor the program is not to argue any of these points. The response from those who favor the program is not to even acknowledge that the points have been made in the first place, but to repeat the original claims as if they are proven already.
Given that all the claims are already proven, there is no need to debate. Debate only gives unnecesary credibility to those who have no basis to their arguments. Never mind that the arguments against are based on some pretty realistic concerns about if the program actually works economically or environmentally, as long as the arguments aren't analyzed there is no need to worry about their content.
At least under Bush it was obvious when counter arguments were being dismissed out of hand and without thought, but under Obama the talk isn't "if you are not with us you are against us" but instead there is the suggestion of bipartisanship and all sides coming together. All sides can come together, if they all agree to do as they are told by the Obama administraiton.
