If you're using race as a proxy for wealth (e.g., black ppl tend to be poorer and the poverty is a disadvantage), then you should just use wealth, not race.
Im reminded of being in a clubhouse sex worker room where I was surprised to find all the other black sex workers had come from significantly more advantaged positions than me; I was the only one who got into sex work cause I was very poor and had few other options.
Maybe being a black sex worker is just extra hard for some reason, to the point that you'll rarely find one who isn't privileged in other ways.
Likely a minor selection effect, but in the worst case could be literal survivorship bias.
I do agree here; I actually think it is harder to earn money as a black sex worker; ppl tend to both prefer their own race and also signifiers of success, and black ppl are both a lower % of the population and less successful.
