I heard someone recently quote a saying to the effect that a millionaire says he's self-made until he's arrested for embezzling, then it's the fault of his environment.

I suspect one reason the capitalist idea so quickly became a dogma or ideology - supporters often arguing more from faith than reason ("the invisible hand of the marketplace," &c.) - is that a decentralised market *looks* as if it should work without regulation, as do natural processes. Its intuitive appeal is so strong that whole schools of economics spring up to explain away the horrible real-world consequences of an unfettered marketplace. (Of course, the ability of this system to concentrate vast amounts of revenue also fuels the support.)

If some day a self-regulating marketplace can exist, it would need more diversity to be sustainable. As long as non-money values and untradable resources "don't count," the market sees (and rewards) the plunder of those intangible externalities as "creation" of wealth.
