Dahs, you're jumping aboard as if Keynesian economics is the ONLY truth in the world of economics. As I've mentioned earlier, Keynesian economics is a THEORY of economics, and fails fundamentally to address HUMAN BEHAVIOR and the effect of human emotion on supply, demand, and consumption. You're coming off as an intellectual snob who sees only his field, and not the whole picture.
If you want to argue that the government is run by Keynesians, that might very well be true (and part of the problem). The US economy isn't run in an economics classroom. It is filled with 300 million PEOPLE, some who make buying decisions and long-term purchases and loan decisions based on EMOTION. And not based on Keynesian theories about when people should buy.
Put another way, is there a rational, sound, economic reason why millions of people would accept ****** loan deals (negative amortization, variable rates tied to LIBOR with outrageous margins, etc.) with little or no chance to see the loan through to its conclusion?
So take your condescending tone back to your classroom. It doesn't work well in the real world.
