Union bashing is dumb story telling to keep the taxes of billionaires low.

Generalizations about "clergy" do not make much sense if you want to cover Iranian Ayatollahs and Buryat Lamas at the same time. Same about unions. The context changes across the globe.
I come from France where the desire from the elite to crush unions is also strong, but the USA is yet another level.
Given that context the unions that do exist today in the USA have been selected for their survival skills more than anything else. Like always you can only reap what you sow
A tram recently got built where my parents live near Paris. They had to involve something like 15 cities, 3 departments, one region, the French state, and the european union. That was lots of people who wanted to have their way. It slowed things down. But it got built anyway and now it works.
The US finds it hard to delegate trust on these things, and parties throw up objections over and over again, either because they want to kill the projector because they want to cover their ass from those that want to kill it.
