This is dead wrong. For all of human history through say 1800 gains in productivity flowed back to the general population in the form of more kids (but no per capita growth), this was the Malthusian equilibrium. Since 1800 not only has the typical person’s standard of living exploded but the typical person works in both paid and nonpaid labor far fewer hours. Roughly the typical person worked 4000 hours a year in paid and domestic labor in 1800 compared to less than 2000 hours a year today.
