I'm a fan of an alternative framing of it, advocated for by people like Blake Masters. I think in a well-run society, you should be able to raise a family on one single income.
Interestingly, Elizabeth Warren (who, unlike Masters, is a left-wing politician) has also used this framing in her 2004 book titled "The Two-Income Trap" [1].
The interesting thing is that Masters advocates for it, not Warren. A living wage has been a common refrain from the US left since the early 1900s. It was a core goal for FDR, as well.
