> Stanford economist John Pencanvel reviewed World War I-era factory data and more recent literature to conclude that exceeding 50 hours in a week leads to diminishing returns

Applicability questionable.

Extra work doesn't make him richer if it results in reduced output. The arguments here are in internal tension.

There’s also the tribal knowledge that you spend the last 10% of the time on 90% of the project. Perhaps every hour after 40 is diminishing, but required to achieve your goal. Could be true, could be a fallacy, but just saying that after a certain point you get diminishing returns maybe misses something either way.
