Why don't more African Americans follow MLK and Malcom X's ideas?

I worked for about a decade in South Central LA some time after the Watts Riot. The irony is that many of the blacks left their neighborhoods "for a better one", only to form a new ghetto on the west side, even more dangerous than the original. The problem is as old as mankind--when youths face a seemingly hopeless future, they join gangs. Once gangs are established (there were hundreds in South Central LA--mostly variations of the Bloods and Crips), it becomes dangerous not to join. Then everybody rips everybody off, including ripping off the government and those that would try to help them. Occasionally the youths wise up and listen to Martin Luther King, Malcom X, even Bill Cosby, but unfortunately too many more callow youths are born and take their place. If I had dictatorial powers, I'd disperse and ter ghetto youths all over the place, and destroy the old neighborhoods, because it's the old gang culture--like mold---that keeps perpetuating the problem. Practically speaking, all we really can do is to keep up the education and treat such ghettos as in need of reconstruction.
