I've always liked the idea of "learning or earning" whereby if you become unemployed you get a welfare benefit to study for 3, 6 or 12 months in university or vocational training and then guided through improving your CV and then you hit the job market again. But I come from, and live in, various countries where there is decent welfare, universal healthcare and deferred interest-free loans or token fee university education so that's in place more or less anyway although it could be formalized and streamlined more. A lot of infrastructure would need to be put in place for such a system to work in the USA.
