UPDATE: Michael Green has written a follow-up post which essentially agrees that $140,000 is not a good national poverty line, but he still has concerns. I have written a new response to his post.

A recent essay by Michael W. Green makes a very bold claim that the poverty line should not be where it is currently set — about $31,200 for a family of four — but should be much higher. He suggests somewhere around $140,000. The essay was originally posted on his Substack, but has now gone somewhat viral and has been reposted at the Free Press. (Note: that actual poverty threshold for a family of four with two kids is $31,812 — a minor difference from Mr. Green’s figure, so not worth dwelling on much, but this is a constant frustration in his essay: he rarely tells us where his numbers come from.)

I think there are at least three major errors Mr. Green makes in the essay:

1. He drastically underestimates how much income American families have.
2. He drastically overstates how much spending is necessary to support a family, because he uses average spending figures and treats them as minimum amounts.
3. He obsesses over the Official Poverty Measure, since it was originally based on the cost of food in the 1960s, and ignores that Census already has a new poverty measure which takes into account food, shelter, clothing, and utility costs: the Supplement Poverty Measure.

I won’t go into great detail about the Official Poverty Measure, as I would recommend you read Scott Winship on this topic. Needless to say, today the OPM (or some multiple of it) is primarily used today for anti-poverty program qualification, not to actually measure how well families are doing today. If we really bumped the Poverty Line about to $140,000, tons of Americans would now qualify for things like Medicaid, SNAP, and federal housing assistance. Does Mr. Green really want 2/3 of Americans to qualify for these programs? I doubt it. Instead, he seems to be interested in measuring how well-off American families are today. So am I.

Let’s dive into the numbers.
