WHAT'S IT ALL WORTH?

I was watching the video for Nas's "Nas is Like". In his second verse he describes what he has reached financially in contrast to where he has come from.

He says in that verse, "what's it all worth / can't take it with you under this earth / rich men died and tried, but none of it worked / they just rob your grave..."

The question stayed with me, echoing, "what's it all worth?"
