Just a residual of the slave mentality. A lot of black folks don't value themselves so they think they can simply buy status. That's why they throw money away on bullshit because in their eyes and the eyes of their foolish admirers it elevates them.
Stop blaming slave mentality for everything.
Most of those mofokrs don't know a damn thing about their own history.
It's attention whoring and keeping up with the Jonses mentality.
