The white people who count aren't under any illusions about why things are the way they are. It's the reason they - again, the whites who count - are the caretakers of the system that was created to give white people the advantages they have today. And no amount of lecturing or guilt-tripping or article/book writing is going to make them alter their system to make it more "fair."
Lectures like that are for people who need to hear something to feel better. It's like masturbating. Feels good but nothing comes out of it. It's good information, I listened to the whole thing, but it's nothing more than theoretical conversation, which we've had plenty of for decades now while our position in this country has continued to stay stagnant and may have even gotten worse.
And for all that, the dude giving the lecture still says he lives in a white community - and the way he stressed it makes it sound like an ulta-white community - and has put his children in the hands of white teachers and his tax dollars toward the continued uplift of the white community he lives in.
