Your "source" is a left wing parroting of the usual "they have more so they can't be victims" canard. Sadly and predictably, you don't know a correlation/causation argument when you see one. Your article's ENTIRE premise is that black people have less stuff so they are necessarily victims of the group that has more stuff who is making the black folks have less stuff.

Why don't you ask why these leftist writers you like to source never discuss the per capita demographic breakdown of who commits the most hate crimes and the group that's the largest victims of it? 

Trust me, you won't like it. 

Your article is a perfect example of racial harassment of whites: It scapegoats white people left and right and basically states that they can't be victims of racism because they have more stuff. That assertion is racist unto itself, so you may actually want to dig for legit data.
