so your position is that central planning will work, the central planner just needs to be intelligent enough, informed enough, and good-intentioned enough? central planning never works, it's not possible without some kind of non-human omniscient overlord. best you can do is give the participants in the market [parents and prospective parents] the most information you can [i.e. screen for genetic abnormalities, low iq, wrong gender, etc.], and let them do their thing. i guess the other thing you can do is not have perverse incentives like a welfare state, because what happens is that the population evolves to be fittest in its environment, whatever that environment is.
