Obama plans on implementing a 'carbon cap and trade' scheme in the US. This is the same system that has been employed in Europe over the past few years and has failed. Obama concedes that the plan will raise costs on Americans. (He appears to be unaware of how poorly the plan has worked in Europe.) The purpose of the plan is to allow the government to choose winners and losers. It is really that simple. Here is a discription of the plan by someone who doesn't like it. (Actually the plan is no good even for those who think it is imperative to cut CO2 emissions.)

I expect Obama to destroy the economy of America, but Democrats will blame it on George Bush.
