I knew someone who was getting significant public assistance to help get out of homelessness.

The requirements were a nightmare. Your employer had to fill out regular forms, the office administering the program had to fill out regular forms, when they made mistakes they'd threaten to take away your housing (and the office frequently made mistakes). If you were employed there were perverse incentives... they would reduce your benefits my MORE than you earned so it only made sense to get a job if the pay would completely disqualify you from the program. It really was torture.
