You've rather hit the nail on the head - companies shouldn't be allowed to use violence (private armies) in order to force people to cooperate. Likewise, government should not be allowed to force terms of employment on employers. When things turn violent is the exact point the government should intervene, no sooner. It should otherwise refrain from interfering with private, peaceful negotiations between its citizens.
Kellogg's is a perfect example here - the employees tried to collectively bargain for higher wages, and the employer decided that the cost of replacing the workforce was lower than the cost of meeting their demands. No violence required, just a voluntary basis for cooperation. This is how it should work.
And yet the power Kellogg's has means that they can just find enough desperate people elsewhere to take their unlivable wage. It's a race to the bottom, and the end is a few massive companies all colluding to pay slave wages. See Amazon and Walmart for examples of this happening right now. People think that market will reach equilibrium, but don't realize that equilibrium will be reached with third world style factories with 12 hour days and dorms for the "employees" and nets outside the windows so they can't even die the way they want.
heh, define "unlivable", these people are clearly still alive. Unskilled labour is usually in surplus. The only reason the likes of Walmart pay as little as they do is because our government subsidises their employees. We've already reached the equilibrium, we've just offshored all the suffering so we don't have to look at it. We still consume goods made in these places. By the way, the factories in places like Bangladesh offer an improvement in quality of life compared to subsistence farming, which is why people work there. Isn't that a good thing?
