I don’t think it eats them up inside. I think they feel entitled to their cushy, well-paying jobs. And of course they still resent whites. At least that’s the attitude of every one I’ve spoken to.
They definitely do feel entitled, but they know they lag behind whites and increasingly, Hispanics, in very basic skills. The open southern border was the death knell for our blacks in the permanent underclass; whereas before there had to be some accomodation to fit them into the workforce, they now have absolutely no economic role (save as consumers of goods & services in the most Godforsaken places in this country).
