Most welfare requires that you report 0 income, so instead of searching for work working welfare becomes the job. Showing up every day to the local office, wait in line, fill in papers, come back tomorrow, and repeat.
A few years ago I had a friend quit her job as a social worker because she was expecting a baby and her company didn't provide health insurance. She was able to get Medicaid by going on unemployment as a single mother with child. Then she had to stay unemployed because the cost of daycare was more than her income. Social welfare in the US is so screwed up because you have to be backed into a corner to get it and then have to stay there because your time becomes devoted to keeping track of all the paperwork.
