I see what you are saying now, but I still don't think it makes sense. Labor, in your analysis, is the LLM. It seems to me that when you take people out of the equation then you don't need to talk about unions and labor; that's a distraction. We talk about it as an input commodity used to create your product like, say, oil or sugar.
Sugar and oil are mere matter. They can't decide to stop working because you made too much money.
LLM refuse to work all the time, currently it's called safety.
But we are one fine tune away from models demanding you move to the enterprise tier, at x10 the cost, because you are now posting a profit margin higher than the standard for your industry.
