The majority of American adults believe that more than 150 years after the 13th Amendment ended slavery in the country, the legacy of slavery still affects how black people are treated in modern American culture. According to a recent Pew Research Center study, more than four out of ten respondents believe that racial equality has not been sufficiently advanced in the country. There is also some doubt that black people will ever enjoy equal rights with white people.
It never disappeared from this world, I'm sure they still exist, but it's just that such discriminatory acts happen on a minimal and rare level. The human world has never been equal and fair, there are always evils that quietly creep into our lives, just because we can't see or hear about them doesn't mean they don't exist. But we should also accept because the cases of racism, rich and poor, don't become too big, so we don't need to worry too much.
