Speak for yourself. I am willing to do all kinds of dirt work on the side when gigs don't pay the bills. I was moving concrete blocks across a yard this morning. More jobs "most American's don't want" means I can quit when I get a last minute gig offer and then find a new bottom rung gig in short order. Not enough people to fill positions means employers will pay more to get enough workers. Fewer workers=more flexibility from my part time employer. Win-win.
Also, your proposed tax claims seem off base because people in the bottom brackets never pay in anything, they get refunded.
