I know y'all are quoting System of a Down, so I want to share a country song about exactly this...because the difference in the musical styles is neat. One of my favorites by Steve Earle: Rich Man's War.
It's a song I've always loved for the direct message of rich people using poor folks as soldiers in wars...but also the way it weaves in a larger economic picture about the decisions by the rich that put people in the very desperate positions that they later exploit.
Truly. I didn't know a song could make me cry until I listened to Billy Austin, a song Earle wrote about the death penalty.
I appreciate that you gave it a listen! Hopefully you appreciated it
