I apologize to everyone.

Someone please explain to me the justification for comparing lower class blacks with middle class whites, and not lower vs lower and middle vs middle.

I've noticed this with America - social problems tend to be expressed as race issues rather than social issues. It could be because there is a lot of racial awareness and idenfication, but far less (for want of a better word) 'class' awareness.
