Without getting into details, I feel that the racial inequalities in the US are much more socio-economic differences that due to race. Poor caucasian Americans very often face the exact same problems as African Americans do, with African Americans however being disproportionally worse off economically due to mostly historical reasons. Still, the high rates of unemployment, drug addiction, crime, low levels of social mobility, etc. African Americans face are to a large extent simply due to them being poor than them being black in my opinion.
