Exploring Wealth Inequality

Abstract

Many political leaders and pundits consider wealth inequality to be a major economic and social problem. They complain about a shift of wealth to the top at everyone else’s expense and about plutocrats dominating policymaking in Washington. \n \nIs wealth inequality the crisis that some people believe? This study examines six aspects of wealth inequality and discusses the evidence for the claims being made. \n \nSection 1 describes how wealth inequality has risen in recent years but by less than is often asserted in the media. Indeed, wealth inequality has changed surprisingly little given the large economic changes in recent decades from technology and globalization. Furthermore, most estimates overstate wealth inequality because they do not include the effects of social programs. \n \nSection 2 argues that wealth inequality data tell us nothing about levels of poverty or prosperity and thus are not useful for guiding public policy. Wealth inequality may reflect innovation in a growing economy that is raising overall living standards, or it may reflect cronyism that causes economic damage. \n \nSection 3 examines the sources of wealth for the richest Americans. Most of today’s wealthy are business people who built their fortunes by adding to economic growth, and some have created major innovations that benefit all of us. The share of the wealthy who inherited their fortunes has sharply declined in recent decades. \n \nSection 4 looks at cronyism, which refers to insiders and businesses securing narrow tax, spending, and regulatory advantages. Cronyism is one cause of wealth inequality, and it has likely increased over time as the government has grown. \n \nSection 5 explains how the growing welfare state has increased wealth inequality. Government programs for retirement, healthcare, and other benefits have reduced the incentives and the ability of nonwealthy households to accumulate savings and thus have increased wealth inequality. \n \nSection 6 examines whether wealth inequality undermines democracy, which is a frequent claim of the political left. Research shows that wealthy people do not have homogeneous views on policy and do not have an outsized ability to get their goals enacted in Washington. \n \nIn sum, wealth inequality has increased modestly but mainly because of general economic growth and entrepreneurs creating innovations that are broadly beneficial. Nonetheless, policymakers should aim to reduce inequality by ending cronyist programs and reducing barriers to wealth-building by moderate-income households.
