Wisconsin’s Act 10 did not ban voluntary union membership.
Never said that it did. What I am saying is unions have their place. Privatized government contracts that go out end up in someone pocketing a lot of cash and some contractor paid without benefits doing the work.
People are getting rich off of privatization of what used to be solid middle-class jobs. the management skims the money and pays service level non-benefit jobs to contractors. I don’t see how that helps the economy more than solid steady jobs.
