Newsweek has an interesting piece up on the growing black gender gap-as women go to college and enter professional fields at higher rates than men. Shocking statistic, 47% of black women between 30-34 have never been married (compared to 10% of white women).
Well, if you assume the axiom of sameness this is something that might blow you away, but women in West Africa do the farming and operate stalls in markets as free agents. They’ve been doing this for generations . As James Q. Wilson has noted, many African-American “social ills” have their cognate, and likely precusors, in the West African cultural matrix.
Of course, I’m not trying to say that the situation should make anyone happy or complacent, but the independence and self-reliant economic productivity of black women has a long history. This is a not just the out-growth of modernity (and as one train of thought hinted in the article, the result of discrimination against black men in white America).
 The intensive plow-based farming that requires a large quotient of upper body strength that dominates in much of riverine Asia tends to require men of course, going a long way to explaining the dominance of the male gender on the village level in India or China. In these societies it is plausible that women don’t have the physical durability to maximize yield in dense plots and keep up a level of subsistence.
