I never studied those different schools of thought, so I can't comment about why one is any better than the others. Even if I could make an argument for one system in favor of another, our politics are too messy to be expected to follow any single coherent theory. In trying to figure out my preference for which direction the country should go, I try to determine who is lying to us (Paul Ryan), whose arguments make no sense (Eric Cantor), who seems to be trying to get to a solution (Obama), and that sort of practical thing.

At the moment, I think they are all blowing it by insisting on immediate spending cuts. That's the last thing the economy needs now, IMHO. It's just that Obama is blowing it less than the GOP.
