One of the most harmful pieces of residual baggage left over from the Cold War is that policymakers are still loathe to talk about inequality. After all, boiled down idiotic simplicity, capitalism is all about growth and socialism is all about equality. But now the Cold War is over, and it’s time for economists and policymakers to once recognize inequality for the social ill that it is. Communism failed; it’s time for market economics to take a swing at this problem. (Fortunately, this is already happening, at least to some degree.)

This post over at Econlog got me thinking:

Fifty years ago, a college-educated male was much more likely to meet and to marry a female with average or below-average cognitive ability than is the case today. Stratified marriages will produce stratified children. As cognitive skills become increasingly important determinants of wealth, we may see a reduction in intergenerational mobility across income classes.

I had never really considered social inequality as a biological challenge, only as a economic one. But according to the research cited above, not only is wealth stratified, but the inherent biological ability to succeed (intelligence, dexterity, charisma, etc.) may be increasingly segmented as well. Now there’s a touchy issue to approach.

On the other hand, the notion that suddenly this trend is happening in America over the past 50 years surprises me and seems a bit odd. In theory, throughout history wouldn’t people of greater ability have risen to the top, and then sought out mates of similar quality? But were that the case, we would expect biological disparity to be much greater than it actually is, and we wouldn’t expect to see genetic diseases riddling noble lineages. (Though we might chalk the latter up to inbreeding – choosing mates similar to yourself backfiring; it seems nature has a solution to everything.)

And so it remains a riddle for the time being…
