Avg person only cares because they are on the short end of the stick. The better off financially someone is the less they tend to care and even start to say black people are the problem.
Most of the posters on this site who go hardest are in terrible financial situations.
This is a flawed logic since it's proven that the higher you climb the corporate ladder, the more you become exposed to institutionalized racism, which is a byproduct white supremacy (you should know this if you have ever worked in the corporate world). And a lot of people at the bottom don't care cuz they just want to get by and exist. Talking about race and white supremacy is the last thing on their minds. So, it's difficult to put it one class, since it's mostly a mentality thing and level of knowledge.
Muhammad Ali, Kareem Abdul Jabaar, Jim Brown, and Harry Belafonte were at the peaked of their careers, when they were marching. So, financial factor is and has never been factor.
