seems like prisoners dilemma. if all businesses pay workers better the business does better and society benefits. if a lot of businesses don't invest in workers society isn't as well off. but all businesses need to act or the cheaters prospers.
Businesses would pay workers better if there were less artificial barriers to hiring--employer mandate--and more competition for resources--limiting H1B abuse. Of course, this is only up to a point where it is economically viable to remain a going concern.
That will be easier to accomplish with the pitchforks.
