You describe WHAT is happening, even though the post you replied to deals with the question WHY.
Of course the little black kids in the ghetto won't have that thought process, they just do what they learned from the people around them. However, it's a result of a dozen different socio-economic factors.
Poverty breeds crime. Crimes committed by non-white people lead to more racism towards them. Racism reduces the chances of non-white people breaking out / succeeding in life, which perpetuates their worse economic status. Repeat till infinity.
It's a vicious circle. Saying that "black people commit 5x more crimes than whites, it's obviously because they have crime in their genes lolol" is the most retarded argument ever.
Being poor has everything to do with it.
