According to a recent study1, unlike the growth patterns in the 1950s and 1960s, the majority of full-time workers did not share in the economic growth of the last forty years.
Had the income distributions of the three decades following World War II (1945 through 1974) held steady in the following four decades, the aggregate annual income of Americans earning below the 90th percentile would have been $2.5 trillion higher in the year 2018 alone. That is an amount equal to nearly 12 percent of GDP—enough to more than double median income—enough to pay every single working American in the bottom nine deciles an additional $1,144 a month. Every month. Every single year.
The median income for all adults with nonzero income was $42,000 in 1975 and it grew to $50,000 by 2018. Had income for this percentile grown as the same pace as the economy, it would have reached $92,000. In other words, their income growth captured only 17% of the growth that occurred in the whole economy.
