Now, I understand that no sensible person actually believes that "green jobs" are going to save the economy.
Saying that we need green jobs is just a way of justifying increased government payments to corrupt shell corporations like Solyndra. I bet the perpetrators of this fraud are actually pretty amused that it worked.
But here are some facts: even if the maximum good things happen, the impact will be negligible. And it is not likely that anything good will happen.
