Being quite the rap fan myself (and having access to the underground rap scene) here is what my take on your question is.
My friend (middle class african canadian) started rapping in grade 10.
my other friend (middle class white canadian) is also a rapper and a very skilled free-styler.
I know intricately their childhoods and here’s what i see when analysing their lyrics.
My white friend doesn’t really rap about material things. He was born into a fairly wealthy family (they own a cottage that is bigger than my old house) and he has lived the care free suburb life.
He raps about dominance. Like me he is very competitive, his lyrics usually are to the point of showing superiority (like all egotistic raps) but he likes to do it in a more creative way than just saying how much money he has.
To quote one of my favorite lines of his “You’re fuckin’ stupid, like sex with a dumb person”. This is the typical genre of his lyrics.
The other friend (the african canadian) is actually an extremely skilled lyricist. He doesn’t rap about dominance. He was always the leder of the gang. (the white one is pretty much his shadow).
He raps about honeys and partying. When we were kids we were obsessed with girls and we didn’t know why. Now he raps about his sucess.
however, there are a few exception aspects of the duo. The africans new songs are absolute dynamite. his lyrics now encompass “life issues” so to speak. And the white guy has an impressive command of the english language, especially in his “rap-battles” (yes i said it, rap battles).
Rap is an art where you sell yourself as an idol through song. You can’t listen to rap without hearing them promoting themselves, it’s just not possible.
that being said we can ask, what should rappers rap about?
well, what should a singer sing about? it’s up to you really, and you should probably sing about more than one thing or risk becoming a one hit wonder.
i feel stupid talking about my 2 best friends as “the white and black guy”. their rap names are Casper and Platinum (respectively)
here is a link to 3 of their very very early songs.

Atmosphere was their very first song.
don’t judge them too harshly, their new stuff is many times better than the ones on their myspace.
Also here is a “rap-battle” between Casper and Quake.
