what keeps mankind alive

This is something to keep in mind this year, both for the self righteous GOP that thinks morality is a simple matter of working and not having sex, and for the self righteous who call themselves democrats who think they are special because they have that cushy job in the gentrified neighborhood. Bonus points if you know the original source of this:

You gentlemen who think you have a mission
To purge us of the seven deadly sins
Should first sort out the basic food position
Then start your preaching, that's where it begins

You lot, who preach restraint and watch your waist as well
Should learn, for once, the way the world is run
However much you twist, or whatever lies that you tell
Food is the first thing, morals follow on

So first make sure that those who are now starving
get proper helpings, when we all start carving
What keeps mankind alive?

What keeps mankind alive? The fact that millions
are daily tortured, stifled, punished, silenced and oppressed
Mankind can keep alive thanks to its brilliance
in keeping its humanity repressed
And for once you must try not to shirk the facts
Mankind is kept alive
by bestial acts!
