"Better areas"
Not every predominately African-American neighborhood is a "hood".
And because they're spineless cowards with no integrity or loyalty to their people & community if they prefer to live in a predominately white community over a black one would be my answer. Same could be said about Africans that take the easy way out and run away from their own people to go live up under cacs. But some people prefer to be individuals and are only concerned with the well-being of themselves and their immediate family and that's fine too
But a large part of the socio-economic problems in alot of black communities in America, have their root in the black upper class, which served as the economic base for the black middle and working class pre-integration...abandoning their communities post-integration to go live in white ones...there were thriving black communities in places like DC, Harlem, Durham, Detroit etc. headed by the black upper class, filled with tons of black owned businesses, black universities, black banks, black sports leagues, black media outlets, black hospitals & pharmacies...all used primarily for the benefit of black people...100's of years of work threw down the drain for whiteys "civil rights act" so we can live in his neighborhoods, fukk his women

and pour our money and talent into his businesses and institutions.
