The Caucasians ended up here with an average IQ of 100. The Mongoloids arrived with an average IQ of about 104. The Negro came here with an average IQ of 85. Why is it so difficult to accept the fact that their low IQ is the reason for their inability to assimilate into a civilized society or even create a functioning society of their own anywhere else on the Earth.
Average IQ doesn't mean everyone of a particular subgroup has that for an IQ, it means statistically that this is the average score.
If IQ was the telling issue here, how does one deal with the fact that of the total of at or below 85 IQ people in the US, 45% of them are white and 32% of them are black? That gives us roughly 13 to 1 (conservative estimate weighted to your side) 85 or below IQ white people for every black one. If IQ was even remotely a significant factor in this then there should at least be a somewhat equivalent crime rate (per 100,000 or other similar metric) between the two groups and I don't believe that is so.
I assert that the only reason that this isn't currently equal or close is that over the ~60 years of great society meddling, the primary target of that meddling was Americas black subset.
I believe that as a target group they are pretty much at the bottom of the barrel for elitist political usefulness and that the effort will switch to concentrate on either the Hispanics, or the general population as a whole.
Black people were "low hanging fruit" as a voting block to be swayed by political largess without alerting the general taxpaying public to a rapid run up in entitlement costs.
Now, there is essentially no effort to hide or mitigate the outrageous expense to provide public welfare, plus, the government schooling system has done a great job in turning out generally low analytical subjects and the percentage of overall population receiving benefits is right at the edge of insuring perpetual reelection of the class distributing the largess.
Remember, it's taken 60 years of focusing on the black community along with the overall ~120 years of progressivism to get us to where we are. The incrementalist creep isn't something an individual signs up for, it takes generations of hammering in sure-to-fail ideas that sound good, and when they fail off to the next. Hammering in abortion, free love, cash assistance for a short time that trends over to perpetual over the years, media pounding racism and differences, clowns like Sharpton and Jackson, etc...
Pre ~1960, north of 70% of black families were nuclear, dad went to work, mom got the kids off to school, bills had to be paid, etc... Now that figure is around 20% (IIRC). That is catastrophic. They didn't just have an IQ collapse to create that disaster, it's been encouraged.
