Digging holes and filling them, working at the DMV...all great make-work jobs.
The levels of Democrat economic illiteracy are astonishing. They actually believe this crap.
It betrays a concept of "work" held by people who have themselves never worked.
And, indeed, most liberals have never "worked". They have "taught", they have "consulted", they have "networked". But they've never dug a ditch, built a building, started a business, sold anything (outside a garage sale, perhaps), met a payroll, completed a project or, to tell the truth, accomplished much of anything.
"Work" is something they see depicted on thirties-era Communist posters.
