Economics departments — breeding generation after generation of idiot savants

It is...a fact that within mainstream economics internal validity is everything and external validity nothing. Why anyone should be interested in that kind of theories and models is beyond my imagination. As long as mainstream economists do not come up with any export-licenses for their theories and models to the real world in which we live, they really should not be surprised if people say that this is not science, but autism!

Studying mathematics and logics is interesting and fun. It sharpens the mind. In pure mathematics and logics we do not have to worry about external validity. But economics is not pure mathematics or logics. It’s about society. The real world. Forgetting that, economics is really in dire straits.

Of course, economic models, like everything else in today's world, are under the control of our capitalist masters. If they were to really test these models and theories, they would fail miserably. They have to make up all kinds of lies, fudge numbers, and keep repeating the mantra that "there is no alternative" to support their system of capitalism. Hence, their supporting theory and models have become a mythology that only capitalists really believe in, or a dogma that capitalist priests keep preaching after it has long failed to explain anything happening in the real world.
