Some people can't quit (or their families would be homeless, etc.), are only home to sleep due to time constraints, and only get paid enough to keep the cycle going.
There's a spectrum.
Homeless is still a choice.
So is suicide, but usually both are colloquially implied to not be an actual choice due to how dire they are.
I haven't been to prison but I get paid for my corporate job, I get to go home, and I can quit.
