I have a slightly different take on it.
Blacks were heavily persecuted until the 1960s. They were simply not allowed access to jobs and education.
Then, when Civil Rights and Voting Rights finally relieved them of this great burden, and they finally had the potential to get on that bottom rung of the ladder and start climbing up (as had various immigrant classes: Irish, Italians etc.), LBJ played an INCREDIBLE DIRTY TRICK on them: The Great Society.
Because of G.S. welfare, there was little economic benefit for many blacks in taking the lowest paid jobs, and hence starting a multi-generational climb.
I’m not saying there are no genetic or cultural differences. But let’s be honest: How many of us would go to our jobs if we could make as much money without working?
Some would, for the sake of dignity and opportunity ... but, many would not, I dare say. (Even many with good intentions might choose less economic pursuits, like writing poetry or pursuing that elusive dream career in sports/acting etc.)
Of course the Democrats thoroughly protect and perpetuate their travesty of so-called compassion that was started by one of our MOST EVIL Presidents: LBJ.
I continue to hope that 8 years of Trump will allow a much higher percentage of blacks to opt for dignity and patriotism. I am certain the great majority in the Trump movement will embrace and honor all blacks who make this effort.
Expelling the 30 million wetbacks we now have will surely lower black unemployment substantially....and will increase the wages of those in lower level jobs.
