There are a lot of words that have nothing to do with the claimed measure.

I'm still trying to figure out how he reached the conclusion that it takes 63 minutes to earn $1 in the US

And it's silly. A person earning $100 a year is not "twice as poor" as a person earning $200 in any meaningful sense; both are extremely poor and will require essentially the same amount of public support. But this metric treats the difference as so huge (80 hours to earn $1 vs 40) that it drowns out any differences in the rest of the income distribution.
