On crimes I disagree, because committing violent crimes and being caught for them tend to be fairly correlated; crime is rarely a one-time thing, and criminals get unlucky or are stupid too.

As for elites -> more children, since there were various routes into "elite" for smart/competent/etc. people (the church in various roles, not all of which precluded reproduction; skilled trades/guilds, etc.), it did have a positive effect in amplifying traits (intelligence, etc.) which I think people broadly support (I do). Similar to the assortative mating issues with colleges and elite workplaces today.
