>the amount of labor being generated per person has not really changed

im not really understanding what you mean. i dont get how labor is generated, in particular. do you mean to say the amount of total hours dedicated to labor per person or something else?

he's referring to labor productivity, e.g., the economic value produced per unit of labor input. it also _has_ changed significantly, as seen here: https://fred.stlouisfed.org/series/OPHNFB

however, unit labor costs has also been increasing (although they remain variable): https://www.bls.gov/opub/ted/2026/productivity-up-0-3-percen...

Probably to referring to hours worked, eg. https://fred.stlouisfed.org/series/AWHAETP
