To continue the discussion, in a very general sense, highly-paid workers and good entrepreneurs can “afford” more children than their poorer brethren. This will make a difference on the margin, and as a result, on average the top 50% of earners will have more children (say, 3.2) than the bottom 50% of earners (say, 2.5). Society should be expected to change toward “smarter” or at least “sheepier” population. “Sheep” in the Christian sense at least is a term of praise not insult. A sheep is a moral person. What remains is to make the shepherds, the social natural elite, economically astute.
Capitalism, they say, contains in itself the seeds of its own destruction, because it finances the emergence of a leisure class of intellectuals whose main occupation is denouncing capitalism. G.A. Cohen was one such miscreant. For the health of society, he must be bled. And by the end of my eBook, he is an exsanguinated corpse.
