For heaven's sake!
Before 1940's where did employees get "health coverage"? They bought their own. Do you know why employers started offering health coverage? They did it because the government froze wages! Yes, your beloved government froze wages, so "corporations" had to find another way to compensate employees so that they, you guessed it, didn't leave. Employees need to look out for themselves. If this means they unionize, then so be it.
Every time you say "we need a law" to FORCE (men with guns will do the enforcement), you give up a liberty. I will not give up any liberties. So, I oppose this idea, STRONGLY.
