If we could check the average IQ of these feral, black youths, it would probably average about 80-85. They simply can't adapt to a civilized society. Until America finally faces up to the fact that it's time to sterilize these uncivilizable cretins, decent blacks as well as the country as a whole will be held back. The total amount of wealth wasted on these feral beings due to their criminality and lack of production totals many billions. Sterilize the bottom 20-30% of the black population, and things will improve dramatically. Meanwhile, much harsher measures should be taken against these thugs. Much harsher. Or we're headed for a race war.
Wisdom and intelligence are orthogonal measures
