This post reminds me of a 2015 news story about entrepreneur Dan Price (Gravity Payments). He made headlines for his company's living wage described as a point, which he set at 70k, below which a person's finances are a series of trade-offs--medical treatment OR car payment OR vacation OR something else. Above 70k the trade-offs were increasingly qualitative, only.

Whatever you think about Mr Price or his math, I still believe this is the most intuitive description of a "living wage" as a concept.
