My number comes from the Employment and Training Administration, the part of DOL that reports UI claims http://www.dol.gov/ui/data.pdf page three gives the number collecting from all programs.
Your 20 million is still way off, even counting tot a l unemployed…Hell, it's higher than the total number who say they want a job, regardless of whether they're actually doing something or could accept a job if offered.
Therefore, since the world has still/Much good, but much less good than ill,
And while the sun and moon endure/Luck's a chance, but trouble's sure,
I'd face it as a wise man would,/And train for ill and not for good.
