Hmm

I didn't know that "drunks, drug addicts, and homeless people" from your example work at factories.

Well, if we're talking about them, they almost have nothing to do around the clock (although homeless people might have something to eat), so they have plenty of time to reflect, plus they don't always have a partner, plus they don't always have the opportunity to eat even worms, plus not every time a neighbor will lend money to get high. Factory workers have all the above-mentioned joys more stably, so I decided that you were talking about them.
