I agree that austerity doesn't work; the proof is self-evident. But capital markets have proven to be the best way to maximize wealth. Setting up good regulations to ensure less wealth aggregation is a political problem, not a problem with capitalism itself. Greece should have the right to assert its own sovereignty. Right now they are being tyrannized by the Euro. They could leave, but that won't solve their problem. They devalued their own currency many times in the 20th c, and it didn't solve their structural problem. There is nothing remotely fear mongering about saying that communism does not (cannot) work. Its just a fact, borne out by history. The Chinese only became prosperous when they shifted to a capitalist model. They are communists only nominally.
