I have and my experience was that you will never get paid what you’re worth - if you’re talented.
So if you want to argue that people with less talent can make more money with unions, I would agree... in the short run.
Eventually talent will seek other means and leave the unionized industries. The brain drain will have two negative results, reduced overall productivity and a union demanding more and more for its members who produce less and less.
Ultimately, the company produces worse product and recieves less revenue. Less money to pay the hungry union members who demand even more.
Finally the company says fuck this and moves its production to another country where people will work harder for less.
The whole thing will be blamed on corporate greed and will be used as a rallying call to socialism. ‘Cause that’ll fix it.
