Errors in the research of Emmanuel Saez and Gabriel Zucman marginalrevolution.com/margi…

Not surprised. Their 2019 work that claimed bottom decile earners paid same/higher tax rates as billionaires calculated tax as % or income by excluding SNAP from the denominator but *including* taxes paid with SNAP in the numerator. This gave some low earners effective tax rates >100%. Saez and Zucman just excluded these people from the study to avoid raising eyebrows. They are over-credentialed frauds.

Replying to @dwarkesh_sp @pawtrammell
Piketty doesn't replicate in the data.
Not across country or time.
It doesn't even make sense, when R (rates) < G (growth) asset prices RISE relative to wage income, increasing relatively inequality.
So it's nonsensical. Well intentioned nonsense.

It's time for a Emmanuel Saez and Gabriel Zucman tax on university professors. A special tax to shore up public pensions. Who could be against taxing the socialists? @elonmusk @BillAckman

@RBReich be like this to his Berkeley grad students when they ask him about the marginal revolution take on Saez-Zuckman
