' it's because there is a complete lack of responsibility in the black community which has become dependent on everyone else taking care of
them. '
That's called blaming the victim FYI, and it is pretty easy for a person in a priviledged position to do; Now i'm not saying that any of the problems you claim exist are not problens, but i am saying that the cause goes deeper. (like most things in life, there is usually on simple and clear answer and it is usually wrong - life resists simplicity)
You could look at things from a class perspective instead of a race perspective - i'm sure that the chances of ending up in prison are much higher if your parent's income is lower. So you can just 'blame' everything on poverty - and that view isn't wrong - but the fact that poorer people tend to be black isn't a coincdence either.
You can look at things from a feminist perspective and you'll see a sligthly different view of society - women tend to have lower incomes, on average, yet the massive majority of the US prison population is male - which just demonstrates a huge culutral component not directly related to poverty.
Again, life resists simple explainations.
Education is a really important part of the problem, and attitude toward learning is a massive factor in educational achievement - that is something which is pretty uard for schools to do anything about, it usually starts at home or in 'society'. Boys and girls tend to pick up different attituded towards learning, and the lack of male role models in primary/elementary school definitely hurts male achievement. Boys end up thinking the 'learning'/academics is for girls - and then being put in special placement or diagnoised with some 'condition' (which is usually that they don't act like all the good girls - and thus it is pretty accurate to say they have a 'condition', it'w called being a boy, being interested in guns and knives and other things which are banned in elementary - even in their creative writing) and this just serves to discourage them further.
There are a huge number of problems facing american society. But blaming the victim doesn't help. It's not the boys fault that his 'boy culture' likes explosions and video games; it's not the black kid's fault that prison sentences for blacks tend to be longer; it's not a woman's fault that employers are likely to offer a lower starting wage (and get away with it, but they're being good little capitalists)
It is alk an in-built part of the culture; which includes racism. I mean, even with the same rate of arrest and conviction, longer prison sentences push up the % of black inmates. That assumes no racism on the part of the police, but indicates institutional racism on the part of the judicial system.
You can't simply ignore race, class and gender. Discrimination is real, and blaming the victim is usually a simplification at best.
