Some Democratic presidential candidates say that America's economic system is badly broken and in need of sweeping, structural change. In its new Distributive Financial Accounts data series, the central bank offers a granular picture of how American capitalism has been distributing the gains of economic growth over the past three decades. Matt Bruenig of the People's Policy Project took the Fed's data and calculated how much the respective net worth of America's top one percent and its bottom 50 percent has changed since 1989. He found that America's superrich have grown about $21 trillion richer ... while those in the bottom half of the wealth distribution have grown $900 billion poorer. Notably, this measure of wealth includes liabilities. And it does not include consumer goods. But if one did include the Fed's data on the distribution of consumer goods, the wealth gap between the top one percent and bottom 50 would actually be even larger. In 2011, Michael Norton of Harvard Business School and Dan Ariely of Duke University published a study on Americans' views of how wealth was distributed in their society, and how they felt it should be distributed. They found that, in the average American's ideal world, the richest 20 percent would own 32 percent of national wealth. In reality, the top quintile owned 84 percent as of 2011. And that share has grown in the intervening years. Today, the one percent alone commands roughly 40 percent of all America's wealth.
