Could the growth of per capita income be in part due to adjustments in workforce?
The income of males 15y or older grew 6.5%/year between 1970 and 1980 and the male workforce grew from 55MM to 78.6MM. Female income grew at higher rate (from lower base) and more importantly the workforce grew from 51MM to 80MM. The recorded per capita growth of 10%/year is in part due to more people having a job.
