No, the people that love rap just decided they felt sorry for the white rappers and bought there songs and made them rich cause they was nice:)Don't laugh this was just as good of answer as your question was:)
Yes. Everyone used too think that white people couldn't rap and then Eminem came up. Dre Dre risked his carrier for him and it paid off. After everyone saw how Eminem could rap other white rappers came in too the business. For ex: Mac Miller, Lil Wyte. Eminent was the first successful white rapper.
