But I'd point out that, if one makes social responsibility particularly onerous on individual businesses, "You want a workforce? ... pay up" may reach equilibrium not by people paying up but by fewer and fewer wanting a workforce. Then everyone is poorer.
At the end of the day, businesses are started and run by people. Pro-little-guy positions like "tough shit, pay up" are aggressive stances not just against abstract legal entities but also against often-well-meaning individuals who aspire to offer products and services. Even people strongly aligned with European social democratic values agree that the government can't do everything, so if you want locally produced products and services you have to ensure that the conditions are suitable for people to do that.
Yet, somehow I don't think we'd feel the same sort of emotional satisfaction from "You want jobs? Tough shit, stop voting for policies that make it hard to offer them."
