I agree with you, but we should also throw in some aspects of hip hip culture (I like rap and hip hop a lot and listen to a it a lot, but every song is about drug dealing, gang violence, or sex - or some combination of that. It is way too common for popular artists to be killed at parties, clubs, or when they go home.). We also have to recognize that parenting plays a role. Kids don't have much of a chance in life when their parents either are not around or don't care. It's all too common for kids in the inner city to be raised by great grandparents because the other 2 generations failed them. Moreover, the biggest problem in inner city areas is not direct racism, white on black violence (there is actually around 11 times more black on white violence than the reverse), or police violence, it's black on black violence.
That all said, due to previous generations of redlining and white flight, most concentrated poverty in this country is in black neighborhoods. There are lots of white people that grow up in poverty, but poverty in white communities is seldom concentrated. Meaning that most white kids that grow up in poverty know people that are not in poverty. So they may have friends whose parents own businesses, other friends whose parents have good jobs at great companies and so on. Many if not most black kids that grow up in poverty, grow up in concentrated poverty where everyone they know is impoverished like they are. This is almost entirely due to past institutional racism and it is a huge obstacle to climbing out of poverty.
