Hip-hop's always reached out to kids. If you look at the last 10 big albums it might seem ironic. But when I look at the history of this music it's always had a lot of positivity.
Adults get more confused by social worker jargon. Unlike children, they are also less likely to see two sides of an argument, and they no longer think they can make the world a better place. That can make them rather boring, I suppose.
