I'll admit I don't understand all the history behind this but from what I understand there are lots of historic racist reasons why black families are, statistically, poorer than white families. It was very hard for them to buy properties and so for that wealth to trickle down generations. Crime is linked to poverty and black families are more likely to be poorer than white families.
I don't know if any of the two parties in the US are more responsible than the other but I don't think that matters, I care more about what they stand for now.
And while those racist laws are no longer the case, it's quite hard to fix the problems they've caused.
Who are "they"?And they have the nerve to blame others for it?
