In this case, it appears as though you can draw a straight line from racial redlining policies to the current status quo elite profession pipeline.

While you're correct that it's a question of class — class is unfortunately downstream of racial policies the long term effects of which we've never quite fixed.

No, the disadvantage is racialized. White households at the 10th, 50th, and 90th percentile of income live in neighborhoods where the median income is a double digits percentile higher than black households at the same income level, and the effect amplifies the lower your household income is.

Questions of class are questions of race because in America, the median wealth of black households is 1/8 that of white households. Apart from that, even upper middle class black people tend to be excluded from these opportunities because tech entrepreneurs live in upper middle class white neighborhoods instead of upper middle class black neighborhoods. It’s a chicken and egg problem.
