After the early decades of the twentieth century, many nations implemented policies at odds with this ‘pure market’ vision of work and labor. Most have wage regulations, for example, mandating a minimum level of pay. But the justice of minimum levels of pay is disputed, with some theorists arguing that disallowing a person to sell her labor at a price she judges adequate infringes on her personal liberty. According to many libertarian thinkers, our labor is an exercise of our bodies or our talents, each of which we own in a way akin to our ownership of private property. To disallow someone the right to sell their labor even at a very low cost thus infringes on their rights of self-ownership. (Mack 2002) The fairness of wage differentials is also disputed. Should wages track the economic value of a worker’s contributions or their effort, or are wages primarily an incentive to encourage worker commitment and motivation? (Heath 2018, Moriarty 2020) Some theorists have proposed that inequalities in pay ought to be eliminated altogether (Örtenblad 2021), while some supporters of an unconditional basic income, in which individuals receive regular payments regardless of their working status, see it an alternative way to ensure a sufficient minimum income, one immune to workers becoming unemployed (van Parijs and Vanderbroght 2017).
