In this update I will post a bit on black people's situation in the US today. I will happily ignore all the historical stuff, and focus on what things are like right now.
Since the 1950s there have been huge improvements. Back then black people worked in specific trades and jobs. They could be gigolos or private drivers, for instance. Black people had no political rights in many states, especially in the "deep south", and few civil rights. Additionally, everything was separated: Black people went to different schools, different public bathrooms and so on.
After the Civil Rights Movement there was put an end to the segregation. However, today the black community is split instead. One part is doing as well as the white population. They have as good jobs, health insurance e.g. as the white people. There is an increase in black political leadership, there's a black president and so on.
However, this is not the majority of the black population. A large proportion is still not equal to the average white people, and some groups are worse off today than earlier. Formally, they are given the same opportunities, however they live in areas with a high rate of crime and drug abuse, they have jobs with minimum wages, many have HIV/AIDS. Black people go far more often to prison than white people, this can also be seen as racism in the police and legal systems. Actually, more black people are in jail than in the colleges and universities, this might be a result of education being expensive in the US (Here I'd like some comments).
If higher education is expensive, this will help keeping the rich people rich and preventing the poor from becoming rich and successful. It stabilizes the society, however fighting crime, drug abuse and having people in prison requires enormous resources. And it's ethically wrong. In the US, people supposedly have the same chances, but if you can't pay for an education, this isn't really the case.
If the black population is to become a more functional part of the American society, the minimum wages must be raised, entry to colleges and universities should be practically free and health insurance must be removed. Regulating prices on housing could also be a good idea, because it would prevent the slums from becoming greater.
I don't believe any updates will follow on this topic, unless I am requested to. Please comment on the education system in the US!
