How has race and racism change in America over the last hundred and fifty years?
Do we still live in a segregated society and if so, how does this segregation affect both whites and non-whites?

The united states has a somewhat complicated history when it comes to racism, a history of many years of slavery and also a segregationist history, where blacks were seen as a kind of virus that should stay away from whites. In general, a lot has changed in American society, but there is still a natural division, because of history, when it comes to blacks and whites. For example, black neighborhoods and rich neighborhoods. There is no more segregation, what exists in the United States is a class division that is historically based on class division.
