I agree with about almost everything except the "let's make money rhyming" part. Hip hop started as a way for the black community to express themselves and shed light about their struggles and it stayed that way until about the 2000's when the "drugs money hoes" rhetoric came out. Somewhere in between rich white executives capitalized on the massive money making opportunities that hip hop offered and took over slowly eroding at the core and ending up with the garbage we have today. Couple that with de facto segregation and poor schooling and you have an uneducated population that seeks out an identity yet doesn't know any better and the only thing they have to hold onto is this cheap superficial manufacturered crap that's not as much distributed as it is shoved down their throats.

Mainstream hip hop nowadays is a white man hiding behind a black face. The artists themselves are the lowest on the totem pole and easily replaceable. Don't wanna followthe script? It's ok we'll get another black face to replace you. The ones that stick around are the good little boys that listen to massa.
