This is the problem with using averages to compare people. You can't take all the poor whites, all the middle class whites, and all the rich whites and dump their incomes into a spreadsheet and average it out and say "White Privilege" like the media has done for 7 years now. All the major new outlets from BBC, ABC, CNN, to MSNBC, CBS, and PBS have run stories that basically ask us to look away from "The Poor" and only look towards "The Minority Poor". The same way "black lives matter" asked us to look away from all the people killed by militant police and only pay attention to blacks killed by police. I find the same people preaching "unity" are the ones that are separating and dividing.
When you analyze ethnic or racial groups you need to split up the members of that group into sub-groups to really know what's going on. We need to focus on real social science and not extremist media narratives.
