I am not a business administrator or economist. I have a liberal arts degree. Utilitarian arguments are interesting, but I would like to explore the ethics of low-wage employment. I see I left out a feature of Alice and Bob's situation you need to know before answering my question. Let's say that the particular area they live in is average, so the cost of living is about $37,000 a year. Is their salary a living wage or a starvation wage?
Still probably a starvation wage, even though it might be easier to live on $37k in rural Alabama than in NYC. I base this mainly on the fact that wages are lowest in the Deep South, and (surprise, surprise) they also have the highest proportion of people on Medicaid and welfare. We can argue about the virtues and vices of free market economic all day, but the fact of the matter is that there is empirical evidence, the absolute, scientific gold standard of what actually happens in the world that shows that low wages are bad for everyone.
