There is only country in the world that has actually attempted a cap/trade plan that is currently being proposed in Congress and that is in Spain. So how has it fared? Does it create a booming green economy that President Obama espouses? Not so much. It actually loses 2.2 current jobs for every new job it creates. Take a look at this report on a study that a university in Spain just completed for the results.
So the question should be that if it didn't work there, how could it possibly work here?
