Do you believe dependence and entitlement mentality played a large role in this? There is a large market to be exploited in predominantly black areas, however it's the Asians, Indians, and Muslims who seem to be exploiting the market gap in the black community. Whites largely see too much risk in investing in a black area.
As for the Civil Rights movement, I think the black community got too caught up into following leaders and organizers. Once King died the leadership fought amongst themselves and played to the crowd so as to garner support. The pressure to produce results lead to race peddling and race blackmail toward large businesses/corporations who would simply pay off the race hustlers to go away. Then came the scandals and instances like Tawana Brawly. Furthermore, MLK was moving toward economic empowerment before he died, however, it was largely based on redistribution of wealth. He never really got that campaign going, however, his successors took it to an unrealistic level.
Nevertheless, black culture now tolerates a high rate of dependency, illegitimacy, lack of education, and violence. Indeed, the only violence they protest against today is the rare white on black violence while ignoring the relatively predominant black on black/white violence. Politically they support which ever person makes excuses for them and is willing to play to their sense of victimhood in an increasingly more tolerant and less racist country. In short, the civil rights movement led to a culture that has done them anything but justice. The fact remains, the "legacy of slavery and Jim Crow" did not lead to the degradation of the black community. For whatever reason, blacks did.
Just to circle back regarding out of wedlock birth rates. In 1965 for the black population the rate was 24%, so there is a direct correlation between that metric, the unemployment rate and the incarceration rate, which if I continue in this dialogue I will address. As an editorial comment, the rate for the white population was 3% and is now 18%. So there are factors impacting that number in all demographics.
On the subject of dependency/entitlement, looking back through history, the government has been present in every major legislative decision in improving the fair treatment of the black population. Abolishing slavery, Jim Crow, school desegregation etc.
Throughout those pivotal moments there have been lost opportunities to embrace self reliance. The bus boycott in Alabama is a perfect example. I can recall my Grandfather, who migrated fom Arkansas to Detroit and owned his own car repair business after working for GM as a mechanic stating verbatim:
"I never understood where the honor was in riding on a bus and sitting next to those who loathe you. They should have started their own G.D. bus company. I would have packed and moved tomorrow and helped keep the buses running for free".
Instead those of the day allowed themselves to be led in the direction of least resistance. When they held out and refused to ride the buses, they unknowingly impacted the city financially, which gave them leverage that they did not use properly.
It would have been a perfect time to start a small transit system by blacks, for blacks.
On the subject of black on black violence, I would recommend that if you have satellite radio, tune into channel 110 at 6 am weekdays, eastern time and listen to Joe Madison. Contrary to popular belief there is a rapidly growing contingent of those like him speaking out on this matter and seeking solutions. Those of us paying attention are not tolerant by any means. Speaking for myself, no one who I can control or is within my circle of influence fits that stereotype.
The institutions of slavery and Jim Crow, absolutely did have a negative impact on the black population. The prospect of hopelessness and more recently as I illustrated with Jim Crow, the end result being an ongoing cycle of generational poverty.
The only positive born out of those wretched systems, was the fact that the black population HAD to rely on one another, because most were equally affected. and at the end of the day, all represented the same subhuman value in this country, so there was no choice except to be united or the sake of safety. The unity brought about then, that was still present through the civil rights era has been lost by a younger and apathetic contingent.
