Capitalism is a moral system that depends on free exchange. Anyone is allowed to hold whatever beliefs they wish, but those beliefs will be tested by reality. If they do not hold up to reason, then a rational person will re-think those beliefs. Capitalism too depends on reason. That which cannot be rationally explained in a free market cannot be sustained.
Capitalism serves no common good for society.
The common good is a term that has no definition. Soros railed against what he calls excessive individualism. Soros all but admits his tyranny is acceptable, where capitalism's benefits are not. His tyranny holds the collective should benefit not those who hold rationality and justice above the mob. By placing other systems at the same level as capitalism Soros does not raise them, but insults the freest form of human exchange.
