You are missing my point, or rather confirming it. Multiple times actually.

1) The reason corporations can do these things is because there's competition for jobs. If there wasn't, they wouldn't be able to get away with it - see tech industry pay and perks, and the fact that people just leave and find another job for a reason as normal as having to work at an office. If there's competition for labor, unions have value - by excluding other labor. That is their only goal.

2) What's wrong with "robot slave labor"? My point exactly, again. Unions protect a subset of workers from innovation. Good for a few newly-useless workers, terrible for society.
