Poll of former Condederate states: 60% of black people, just 19% of white people strongly think the "legacy of slavery and discrimination" make it hard for black people to work their way up. https://www.winthrop.edu/winthroppoll/default.aspx?id=9804 …
I kinda would like to see some more background on how that question was interpreted. The surrounding questions (T15, T16, T18, T19) and even T20 do paint a somewhat different picture. Don't quite see how, but maybe it gets overgeneralized under "everyone is under attack"?
