Sometimes I look at some rappers and think..... he could've paid a years worth of rent for a homeless person with just that watch on his wrist or that chain around his neck.....

Spending so excessively....

Define necessity. 

What can diamonds do except reflect light? But time, on the other hand, when given invites charity. Am I the only one who it bothers? 

It seems senseless greed to feed the "wants" of one's self over the "needs" of others.
