Wait, what? Maybe the Austrian School goes by theory if that, but every other school of economics goes by facts -- including the Chicago School, Monetarists, Keynesians, New Classical, etc.

Economists' whole basis for their arguments is through empirical data and mathematical facts. Saying economists just relies on dreams is absolutely absurd and shows complete ignorance of the field.

Implying economists use anything but data in developing macroeconomic forecasts is just absurd. Give it a rest.

I think you meant that bankers have dreams. They are the ones who invented the CDOs and other financial abstractions.
