If you want to increase supply of labor, that could point to immigration reform. I could get behind a points based system with weighting around skillsets.
If more later is needed,lower the points. If less labor is needed raise the points. This could be addressed annually very easily,and could ease the insane cost of skilled labor.
I am in a low cost area in flyover land, and the last plumbing job was at $120 per
hour and the plumber was moonlighting. Through a company the bid was over $200 per hour. Scarce labor can and will charge whatever the market will bear,as it should be. Immigration,smartly done, could help solve some of those issues.
