I realize you don't know any black people either, but a much higher % (esp black women) are getting college education and subsequently respectable jobs compared to the 50's. Unfortunately forced integration has driven white flight, and schools & other public services are still often effectively segregated along property tax boundaries. The police crackdown on minorities masquerading as war on drugs has also effectively rendered much of the young black male pop unemployable & broken family structure. But it has effectively retained the permanent underclass which is seemingly its purpose; the blatant racism displayed here is its equal partner in crime.
Reforms are very much often effectively driven from the top down, or otherwise conservatives wouldn't be whining so much about socialist this or that ruining society. Or supporting failed top-down policy like the police war.
In terms of votes, a permanent minority underclass benefits poorer whites, who increasing reliably vote GOP in red welfare counties. In contrast it's the relatively wealthy areas which are reliably blue.
What % is that? And what happens when they get educated and raise up? Do you think they go back to the 'hood and hang with gang bangers? Hardly, they move up and out.
Please, the police crackdown with the war on drugs was nothing more than enforcing reasonable laws. Nobody wants to be around them because they refuse to be accountable for their actions. Blaming white people for it won't get them anywhere until they can fix their own shit.
The relatively blue affluent areas are nothing but bi-coastal fuckwits who want nothing more than to pay off minorities so that they don't riot and take what the .01% has siphoned off from the country through offshoring and immigrating millions illegally to boost profits further. It's a game which the black *AND* white people have been played for fools. Name a single liberal, except for a socialist, like Sanders, which has utterly rejected TPP? Did the Great Black Hope, Obama, reject it? Fuck no, he ramrodded that shit through. Has he stopped importing cheap, uneducated, poor, wage sucking labor? Fuck no, he ramrods it through. Did Hillary reject TPP? Fuck no, it was perfect to her and NAFTA was perfect to her Husband.
Face it, your liberal leaders are nothing more than race baiting hucksters beholden to the .01%. Your enemy isn't the average white person, it's the average .01% that feasts on the carcass of the middle class. Your enemy is my enemy and the *LAST* person who'll fight the common enemy is Hillary, because she *IS* the enemy. The quicker you get that shit through your skull the quicker you can fix minority suffering from a lack of real jobs and opportunity.
