I am part of the problem and with your permission I will ramble on a bit in this comment, because I'm on the internet and I can.
It took me a long long time to realise what you said about racism. I can see the bigots, hear the language, observe behaviours and so on, since that's the surface. I can't see the system because it doesn't affect me negatively (not as much and not in the same way). Since I do have black colleagues, some better paid (for example), I won't see the inner workings of that corrupt system.
Of course, once it was pointed out to me, I couldn't unsee it. Yet, I was in a worse position then because of a weird thing.
See, part of becoming aware of the racist system and being able to trace it along its structures down into history is seeing that it was setup through the ages by the conquering mindset of all the colonial countries. The USA is worse off being a child of colonialism but I can see the same in all colonial countries.
And the strange thing is that I do see parts of the system aware of this and looking for change, the kind of change that's really impossible. I see people that try to effect change, but not too much because since white people are at the top they do want to setup the environment for change but not too sudden so as to not be affected themselves. It's good for making a mark on history, but for future generations, not now when I have to eat.
Disenfranchisement is key. The horror of black people and other 'minorities' (are they really, minorities? I look at stats and they say something somewhat different) actually getting involved in the process and taking over the system must be damn scary even to those that talk the talk.
If you don't care, don't vote or can't vote, you may breathe same air but you're not threatening anyone's seat of power so there's no reason to talk to you or stand up for you and you can't own the system.
I didn't get to my weird position. See, I come form a country of white people, but not a colonial country. We're some dust between the pages. The vast majority of people have never seen a black person in the flesh until a little over decade ago.
The main advice my grandmother gave me when I left my country after highschool: don't bring back a black girl or you'll lose your inheritance. Of course, she'd never seen a black person before. People then were doing the human thing of fearing what's different or revering what's different out of curiosity, but the system wasn't rigged (on country level, at least) for race since nobody gave racial issues much thought.
Then something happened: people went abroad and experienced the miracle of white privilege .. in France , Spain, Germany, the USA. And something else happened: many came back.
