I dont think it's quite that simple. Quality matters. Having fewer, wealthier kids can be an evolutionarily superior strategy, given the greater future potential of higher quality offspring surviving cataclysms and being the founders of new populations (e.g. a Mars habitat). My only concern is welfarism, where modern political dogma insists that everyone must have equal income, irrespective of the personal investment they and their parents put into their developing their productivity.
