> Randomizing children at hospitals would likely have big negative impact on society.
I disagree, and I think the opposite could even be true. We are hard wired to protect our biological offspring; if we know that our offspring will be placed randomly into society, we would have greater reason to concern ourselves with the well-being of society in general.
(All successful modern societies have communistic and capitalistic components in simultaneous operation. Capitalism provides the incentive for productivity and communism ensures that incentives can be acted upon by as many people as possible. The most successful societies are arguably ones that balance these aspects well.)
That is precisely the prisoner's dilemma. People have some interest in making society better, but not nearly as much interest as they would have had in improving the well being of their biological children.
