Well, it is called a "living wage", not to be confused with "poverty wage" or "subsistence wage".

I've always taken "living wage" to be the wage required to live in reasonable comfort. You won't be owning any yachts or eating caviar, but you should also not be living paycheck to paycheck unless you're acting irresponsibly with your money.

If you're sharing a house or apartment with one or more roommates for reasons other than romance or saving up for a place of your own, to my mind, that's not a "living wage" - it's mere survival. Whether we believe minimum wage should barely let you scrape by or live more comfortably shouldn't confuse the fact that in many places, it doesn't even meet what's considered "poverty wage" (e.g., it doesn't in my local area).
