Most blacks learn this crap in prison from other loser convicts trying to explain why despite being in this country for several generations longer than Pakistanis, Bangladeshis, Koreans, Vietnamese, Indians, Persians, Armenians, Irish, Italian, Polish and even recent African immigrants, most blacks continue to amount to nothing.
The real answer is the breakdown of the family unit, their utter lack of discipline, poor impulse control, childlike needs for instant gratification, massive chip on their shoulder, an inability to follow simple rules all combined with a low IQ that prevents them from correcting their behaviors.
