In the past, America has been a country with a racist and people with black skin are enslaved. Because blacks skin were seen as uneducated, criminals, prostitutes, addicts or drug dealers etc. This story is true but not able to stereotype that black people as a whole don't forget that black people can succeed in many ways. Looking back the cause of black people behaving like that it can be seen that derives from whites because of the absence of discrimination, bullying, bullies since ancient times. Equality in all aspects would not cause this kind of inequality. Currently, America has a black president now but the concept of an insult black people still exists.
