I want the clever, hard-working children of those in the bottom half of income distribution to move up, and the less able children of those in the top half to move down.

In other words, I think the answer is more meritocracy. I approve of the principle for the same reason my father disapproved of it, because it helps to secure people’s consent to the inequalities that are the inevitable consequence of limited government. It does this by (a) allocating wealth and prestige in a way that appears to be fair; and (b) creating opportunities for those born on the wrong side of the tracks, so if you start with very little that doesn’t mean you’ll end up with very little, or that your children will. If you think a free society is preferable to one dominated by the state, and the unequal distribution of wealth is an inevitable consequence of reining in state power, then you should embrace the principle of meritocracy for making limited government sustainable.

This sentence also appears: "If the history of the twentieth century teaches us anything, it is that the dream of creating a socialist utopia often leads to the suppression of free speech, the imprisonment of a significant percentage of the population and, in some extreme cases, state-organised mass murder."
