Is income inequality holding back the United States economy? A new report argues that it is, that an unequal distribution in incomes is making it harder for the nation to recover from the recession and achieve the kind of growth that was commonplace in decades past.
The report is interesting not because it offers some novel analytical approach or crunches previously unknown data. Rather, it has to do with who produced it, which says a lot about how the discussion over inequality is evolving.
Economists at Standard & Poor’s Ratings Services are the authors of the straightforwardly titled “How Increasing Inequality is Dampening U.S. Economic Growth, and Possible Ways to Change the Tide.” The fact that S&P, an apolitical organization that aims to produce reliable research for bond investors and others, is raising alarms about the risks that emerge from income inequality is a small but important sign of how a debate that has been largely confined to the academic world and left-of-center political circles is becoming more mainstream.
More here. From the report:
Though the share of income from labor and capital, excluding capital gains, has decreased, the share coming from capital gains and business income has increased over time. In particular, inherited wealth has increased since the World Wars and the Great Depression, as Thomas Piketty has shown (14), and with it the earnings from that wealth. This trend is important because labor income tends to be distributed across income levels more evenly than capital gains–so a shift in income composition can significantly affect inequality.
While labor income accounted for nearly three-fourths of market income from 1979-2007, that figure had dropped to two-thirds by 2007. Capital income (excluding capital gains) is the next largest source, but even at its 1981 peak, it represented only 14% of market income before falling to about 10% of total income in 2007. Conversely, income from capital gains rose, doubling to approximately 8% of market income in 2007 from about 4% in 1979. Business income and income from other sources (primarily private pensions) each accounted for about 7% of total income in 2007, up from about 4% each.
In addition, capital income has become increasingly concentrated since the early 1990s–and, despite declines in 2001 and 2002, concentration spiked from 2003 through 2007, with more than 80% of the capital gains realized by the top 5% of earners going to the top 1% alone (15). Capital gains also have become increasingly concentrated and are tied with business income as the most concentrated income source.
