>This line of thinking can be used against almost any form of labor protections
If the government really care about worker well being then the government should directly help them, instead of using company as middleman. For example by providing universal health care or universal basic income.
You seem to be implying a false choice here. Specifically that we (the government is comprised of individuals) can not engage both in labor protections at the same time as we attempt to create a universal health care system.
Right, but you're questioning a position that doesn't really exist. Pretty much everyone that is a strong advocate for labour protections would also like universal healthcare, it's just much more likely we can achieve labour protection in the short term than universal healthcare.
