… is from page 8 of Dartmouth economist Bruce Sacerdote’s excellent 2017 paper “Fifty Years of Growth in American Consumption, Income, and Wages“ (link added):
Consumption for below median income families has seen steady progress since 1960…. These estimates suggest that consumption is up 1.7 percent per year or 164 percent over the whole time period. These estimates of growth strike me as consistent with the significant increases in quality and quantity of goods enjoyed by Americans over the last half century. And my conclusions are consistent with the findings of Broda and Weinstein (2008). Estimates of slow and steady growth seem more plausible than media headlines which suggest that median American households face declining living standards.
