> Teacher's unions (hard to fire teachers, poor quality)

Certainly you can quantify this poor quality and show it's due to unions and not, say, lack of resources?

> Transit unions (mandating 2 drivers per subway car, crazy benefits, etc)

2 drivers per subway car sounds like (at least with old tech) a good thing for everyone's safety.

> Auto industry fighting EVs.

Sounds like this was more the companies themselves, but I don't have the details.

In my view unions are largely a good thing to balance out companies power, but I've also heard stories where they have become too strong. There's nuance to the matter, but I feel like at least the US could use much more and stronger unions.
