The
Economic Policy Institute has a new report out that analyzes the continued trend towards income inequality in the US. It also notes that a large part of this phenomenon is due to the falling real value of the federal minimum wage. According to the authors, "Barring a minimum wage increase, we are poised to break a record in 2006 for the greatest inequality between minimum wage and average wage workers since the end of World War II."
The chasm between the middle class and superrich is well-known and heavily reported on by the major media, but one trend that is also very disconcerting is the fact that the gap between the low-wage and middle class is growing as well.
Additionally, a joint study between EPI and CBPP (Center for Budget and Policy Priorities) called "Pulling Apart: A State-By-State Analysis of Income Trends" found that in 38 states, the incomes of the bottom fifth of families grew more slowly than the incomes of the top fifth of families between the early 1980s and the early 2000s. In these 38 states, the incomes of the richest grew by an average of $45,800 (62 percent), while
the incomes of the poorest grew by only $3,000 (21 percent) .
In other words, the poorest families — who saw an increase in purchasing power of only $143 per year — have not fared nearly as well as the richest families during this period.
Between the early 1980s and the early 2000s, the incomes of the country’s highest-income families climbed substantially, while middle- and lower-income families saw only modest increases in income. During the late 1990s exceptionally low unemployment rates did yield significant gains for low-wage workers and relatively broad-based wage growth. But even the positive trends of the late 1990s were not enough to reverse the tide of growing inequality.
The report identifies several factors that have contributed to the large and growing income gaps in most states. The growth of income inequality is primarily due to the growth in wage inequality. According to the authors:
"Wages at the bottom and middle of the wage scale have been stagnant or have grown only modestly for much of the last two decades. The wages of the very highest-paid employees, however, have grown significantly. Several factors have contributed to increasing wage inequality, including long periods of high unemployment, globalization, the shrinkage of manufacturing jobs and the expansion of low-wage service jobs and immigration, as well as the lower real value of the minimum wage and fewer and weaker unions. These factors have led to an erosion of wages for workers with less than a college education, who make up approximately the lowest-earning 70 percent of the workforce. More recently, even those with a college education have experienced real wage declines, in part due to the bursting of the tech bubble in high-wage industries, but also due to the downward pressure on wage growth from offshore competition.
Only in the later part of the 1990s was there a modest improvement in this picture. Persistent low unemployment, an increase in the minimum wage, and rapid productivity growth fueled real wage gains at the bottom and middle of the income scale. Yet those few years of more broadly shared growth were not sufficient to counteract the two-decade-long pattern of growing inequality. Today, inequality between low- and high-income families and between middle- and high-income families is greater than it was either 20 years ago or ten years ago.
The expansion of investment income (such as dividends, rent, interest, and capital gains) during the 1990s also contributed to increased income inequality, since investment income primarily accrues to those at the top of the income structure. The large increase in corporate profits during the recent economic recovery has also contributed to growing inequality by boosting the incomes of investors.
Government policies — both what governments have done and what they have not done — have contributed to the increase in wage and income inequality over the past two decades in most states. For instance, deregulation and trade liberalization, the weakening of certain aspects of the social safety net, the lack of effective labor laws regulating the right to collective bargaining, and the declining real value of the minimum wage have all contributed to growing inequality. In addition, changes in federal, state and local tax structures and benefit programs have, in many cases, accelerated the trend toward growing inequality emerging from the labor market."
Of course, Bush's obsession with tax cuts has not led to the level of economic growth promised. As
John Irons writes in
Mother Jones, " Gross Domestic Product (GDP), grew only 13.5% since the first round of tax cuts were passed in early 2001, averaging 2.7% per year. The average for similar periods in the past was far better – growing 16.3% or 3.2% per year."
Nevertheless, it is unclear whether a different tax policy would create more favorable incentives for businesses to increase hiring, leading to lower unemployment and higher median salaries. And it is unclear to me whether this would lead to the type of structural changes that would decrease inequality.
Irons argues that the tax cuts in fact
have led to sluggish wage growth for middle class workers as well as weak job growth:
"[T]he tax cuts have also failed to create substantial wage and salary growth. Most Americans depend on their wages and salaries for their standard of living. In a healthy economy, wages and salaries should rise along with rising national income and productivity. A record long period of job decline followed by sluggish job growth has created slack in the labor market and pulled down wage growth below inflation growth in the last two years. Last year, middle income wages grew less than inflation (2.4% vs. 3.4%), reducing their buying power.
But with wage inequality growth being a phenomenon that has existed in this country for decades, I am not sure how large of a role the tax cuts play in all this. Any economists reading this, I would appreciate your insight.
