No, these are using the cost of living numbers for an individual. Cost of living for a family of four is over 2x higher by their same calculations.

So for two individuals making $35 an hour they would be close to affording comfortable cost of living in the cheapest state. Or it we were to make it equivalent to one individual’s income being enough for a family, they would need to be earning like 80 an hour

As I showed in my longer comment, this would make the modern minimum needed to afford average COL raising a family equivalent to a top tier income in 1958. Basically unless someone was a 1%er in 1958 they wouldnt be able to live comfortably today. That is how unsustainably far down our wages have stagnated. 47% of households make less than what it costs for one individual to live comfortably. The median income today might be at a roughly equivalent point when adjusting for inflation, but it is brutally low in comparison to what one can actually buy with what that same value of money bought someone in 1958
