It's not like this is a new debate. The US introduced a federal minimum wage in 1933 after a long push to end non-living wages in sweatshops. From the Wikipedia article [1]:
"Minimum wage legislation emerged at the end of the nineteenth century from the desire to end sweated labor which had developed in the wake of industrialization. Sweatshops employed large numbers of women and young workers, paying them what were considered nonliving wages that did not allow workers to afford the necessaries of life. Besides substandard wages, sweating was also associated with long work hours and unsanitary and unsafe work conditions."
Some other countries have universally binding collective agreements [2] that have the same outcome of establishing a salary floor.
