Commence flaming. I'm ready for it.
There was a time when unions served a purpose. That time has long since expired.
Unions are a response to big corporations. Some of their earliest actions - insisting on being paid in legal tender, instead of private company “scrip”, which was only good at the company store, were fine.
I am not aware of union ever pushing us into war, unlike say the arms industry. And unions have no control over the private Fed and the destruction of the purchasing power of the middle class.
I would agree with you that union shops (compulsory membership) are wrong.
