What could possibly be God's plan for black people? Does the bible mention it?

Throughout the course of human history individuals have suffered but the only two race of people to be persecuted solely due to their race are black people and Jews. Jews suffered more no argument about that but blacks have more recently been put through persecution. For the Jews God warned them not to turn from him or their enemies will ruin them and on numerous occasions, a generation of Jews fail to obey God's laws. But a plan was in store for them and they were given a promise that they would one day come out of their persecution. As for blacks we were given no promise, the bible also doesn't speak of a plan neither were we given the same orders to obey and chose to disobey as the Jews did but yet we have met persecution. It doesn't matter whether or not your only half black, quarter black or less as long as your skin color is dark and you have a black parent your considered black and because of it most other races look down on you for it I know this because many people in my family are bi-racial but because of skin color or having a black parent we're sadly looked down on as black. In America it may be thought that persecution or discrimination has ended but in a way it has not. Natural black hair must be altered to more closely resemble that of other races to be considered "professional" every shampoo commercial shows a white man or woman or any one who may have naturally straight hair. Heroes from comic books are almost entirely white and the few who are black aren't that nice or talked about and numerous things of this sort is shown by the media. As for our own selves we have music videos which portray women mostly our own black women as worthless, objects who's only purpose is to either take our seed or fulfill our needs, and for some reason many black women accept that kind of crap being portrayed of them. Slavery may be over but we still not accepted as equals with every other race, and this discrimination towards blacks seems to be spreading because it used to be a thing in only in America that blacks are looked down on but other races in other countries seem to feel the same way. It has come to the point that many black peolpe who are mixed would disociate themselves as black such as tiger woods. What could God's purpose be for black people if there is any because I have seen the bible mentioning one. Could blacks whether full black or mixed be a race who has no actual purpose besides living and going to either heaven or hell?
