I think it should be Enough™️. Not just enough to scrape by with 3 roommates, or to barely make it on your own, but enough so that you're never a single paycheck from homelessness; enough so you can live on your own, modestly, comfortably, without struggling unduly; enough so that if a medical issue arises, you can handle it without worrying.
People should be paid Enough™️ so that they can do MORE than just live, but so that they can THRIVE. And every day that doesn't happen is a stain on Humanity's record.
