I have some insight into this. I am a late 40's male with "some college". Supported myself by doing a variety of blue-collar jobs through the years. Dismissed from my last "permanent" job in the winter of 2007. (Thank you "compassionate non-profit"!) Beat my head against the wall seeking work, while doing so applied for and won Social Security Disability. Took advantage of what the New York Times deems the "shadow safety net". I am employable -- but not in this economy.
