Why does anyone respect rappers?

I don't understand how people can respect someone who is very vocal about how they think they're better than everyone else. The majority of rap songs that I've heard are about how much money the rapper has. Why does anyone want to spend money to listen to an uneducated moron who can't dress himself talk loudly at you about how he has your money? Then they use their money to go and pollute, thereby killing the people who gave them the money. It makes no sense.
