Whether corporations are people or not is irrelevant because the corporations are acting together to abuse market power at the behest of the people running the corporations to maximize benefit for the people running and owning the corporations, exactly like how the unions are acting together to abuse market power to maximize benefit for their members. All the businesses I mentioned could be unincorporated sole proprietorships and it would still be illegal on the business side and so yes it is still weird that it's legal and ok on the labor side. At the end of the day, in all examples, the mechanism is to corner the market in something and withhold it until price for that something is pushed above the competitive price shrinking the total benefit available and causing dead weight loss to society. The result is the same regardless of who is doing it. Less for everyone, artificially more for the group that cornered the market at the expense of literally everyone else. So I'll say again, it's weird that it's ok for labor to do this and not ok for companies. It should be not ok for everyone because it's universally bad (this doesn't mean there aren't other bad things corporations do that don't hit the threshold of illegality for market power abuse that we should also be trying to fix, it just says uncompetitively withholding is a bad method of trying to deal with those things)
