Government should collect wealth data just like income: Berkeley economists

Perhaps more than anything in recent memory, the coronavirus pandemic has illuminated how wide inequality in America has gotten.

The pandemic precipitated one of the worst labor markets in American history, with unemployment breaching the 20% mark, lines at the food bank, and the stress of a pandemic topping it all off. At the same time, it’s been great for the portfolios of the asset-owning classes, who have seen market highs while working from home away from the risk of COVID-19.

However, there’s confusion about exactly how much inequality there is. It’s extremely hard to quantify and the government just doesn’t have enough solid data about its population, even though it passes laws and regulations ostensibly for public benefit.

In fact, private companies have far better data than the government – and they should be the ones tracking individual households’ money, according to Berkeley economists Emmanuel Saez and Gabriel Zucman.

This is one of the key takeaways from Saez and Zucman’s new research paper from the National Bureau of Economic Research.

“We have little patience for the view that ‘inequality is impossible to measure,’” Saez and Zucman write.

In the past, the two French economists, along with their famous colleague Thomas Piketty, have examined inequality in the U.S. and found it has been widening considerably, often thanks to low taxes — as well as tax avoidance and loopholes.

In another recent paper, Zucman and Saez write that “during the 1980–2020 period, wealth as a whole has been growing almost twice as fast as income. The result is that relative to to what is produced and earned in a given year, the wealth of the rich has skyrocketed.”

“The top 10% wealthiest tax units owned 77–78% of wealth in 2018, an increase of 10 points since 1989... the top 1% wealthiest tax units owned 38% of wealth in 2018, also an increase of 10 points since 1989,” they write.

Their analysis is thorough, but challenging. Because there is no centralized data on wealth like there is for income, it’s been hard to know for sure how things have evolved. Cobbling together available data from Fed surveys, the IRS, and more, the economists have been measuring it every other year, in 2016, 2018, and now in 2020.

Other academics found evidence that the rate of inequality increases were slowing, which would have been good news and evidence that current policy could be having positive effects.

Saez and Zucman’s recent paper refutes any ideas that the current socio-economic framework was improving — even before COVID-19, which appears nowhere in the paper, though it was published in October.
