In an opinion article he wrote for the Wall Street Journal, U.S. Sen. Bernie Sanders, I-Vt., called for an end to "corporate socialism" and made a claim about wealth inequality.

"The wealthiest three families now own more wealth than the bottom half of the country, and they will do everything they can to block our agenda," wrote Sanders, who is seeking the Democratic nomination for president.

The latest-available data back up his statement, and it appears the gap is widening.

The figures

A note about wealth, before we dig in:

Many Americans make a good income, have some savings and investments, and own a nice home. But they also have debt, typically from a mortgage, credit cards or other bills. The result is that even some people with relatively healthy incomes, as well as many poorer people, have a negative net worth — the more technical term for wealth.

Sanders’ campaign told us his claim is based on a 2017 study from the left-leaning Institute for Policy Studies. It used Forbes’ list of the 400 richest Americans and data from a gold-standard federal government source on wealth. Those are 2016 figures, from the Federal Reserve Board’s Survey of Consumer Finances, which are updated every three years.

The study found that the three wealthiest individuals were Bill Gates of Microsoft with $89 billion, Jeff Bezos of Amazon with $81.5 billion and Warren Buffett of Berkshire Hathaway with $78 billion.

Their total wealth of $248.5 billion was higher than the wealth of the bottom 160 million Americans, at $245 billion.

Despite Sanders’ suggestion that the three men would block his agenda, they have expressed centrist political views over the years, and Buffett was a well-known supporter of former President Barack Obama, a Democrat.

Whatever their views, Sanders is correct about their wealth, which is on the rise.

Forbes’ latest annual rankings for 2018 show Bezos, Gates and Buffett still ranked at Nos. 1, 2 and 3, respectively, and that their total wealth was $345 billion.

New federal figures for the bottom 160 million Americans aren’t expected to be released until sometime later in 2019.

For the 160 million people at the bottom of the scale, the study used the net worth figure reported by the Fed and then subtracted automobiles and other "durable goods" such as electronics, furniture, and household appliances, from that figure.

Subtracting durable goods from net worth "offers us a more accurate depiction of household wealth as these items are not easily sellable and neither appreciate nor hold constant their value," the study said.

Some context

University of Michigan sociology professor Fabian Pfeffer, whose research specialties include wealth inequality, was among a number of economists and wealth inequality experts who told us the federal figures used in the study are the best for assessing wealth in the population. He told us that the wealth gap is much greater in the United States than in other Western industrialized nations.

Pfeffer said the top 5% hold more than 70% of all net worth in the United States. That’s compared to 44% in Austria and Sweden, and lower figures in other comparable nations.

Our ruling

Sanders said, "The wealthiest three families now own more wealth than the bottom half of the country."

The latest available figures indicate that the total wealth of Gates, Bezos and Buffett was $248.5 billion, exceeding the total wealth of $245 billion of the bottom half of Americans.

We rate Sanders’ statement True.
