I disagree with this - the system we have is based on money and trust, which while gamed easily, is much less violent, brutal and inequal when compared to other systems that we've tried in the past - such as communism/socialism (the USSR still had a market, but it was based on how much political power you had, rather than pure money - a much more violent game), or feudal systems where it was all about how much land you were born into (or possibly conquered for yourself). Of all of the systems we've tried, this is probably the least sociopathic yet.
