That's where unemployment rates are deceiving.
Actually, unemployment rates - the official ones, anyway - are deceptive by design.
This is the government's definition:
* People with jobs are employed.
* People who are jobless, looking for jobs, and available for work are unemployed.
* People who are neither employed nor unemployed are not in the labor force.

If you have 2 doctoral degrees in the humanities but are working in the paint section at Home Depot because they have better health benefits than any of the non-tenure-track jobs left in academia [i.e. my sister-in-law], you're not unemployed.
