Cover art for Heaven Knows lyrics by Pretty Reckless, The

To me it is about how Fd up society is, filled with greed and people taking advantage of those just trying to get by.

Some guy looking at what how he is taking advantage of people to gain and knows damned well it is wrong: "Jimmy's in the back with a pocket of high If you listen close You can hear him cry Oh, lord, heaven knows We belong way down below Sing it Oh, lord, heaven knows We belong way down below Way down below, way down below"

Hooker doing crap she hates because she doesn't see options: "Judy's in the front seat picking up trash Living on the dough Gotta make that cash Won't be pretty Won't be sweet She's just sittin' there on her feet"

Saying everything is just crap and it gets worse: "I've had better days, man I've seen better days I've had better ways, man I know better ways"

God would be judging all of this, and not approving "Oh, lord, heaven knows We belong way down below"

seems like each part of the song seems to fit this mold.
