Nick Hanauer and David M. Rolf in Time:
Like many of the virus’s hardest hit victims, the United States went into the COVID-19 pandemic wracked by preexisting conditions. A fraying public health infrastructure, inadequate medical supplies, an employer-based health insurance system perversely unsuited to the moment—these and other afflictions are surely contributing to the death toll. But in addressing the causes and consequences of this pandemic—and its cruelly uneven impact—the elephant in the room is extreme income inequality.
How big is this elephant? A staggering $50 trillion. That is how much the upward redistribution of income has cost American workers over the past several decades.
This is not some back-of-the-napkin approximation. According to a groundbreaking new working paper by Carter C. Price and Kathryn Edwards of the RAND Corporation, had the more equitable income distributions of the three decades following World War II (1945 through 1974) merely held steady, 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.
