Discussing American Income Inequality

This chapter of the textbook discusses many changes in the American Economy, and speaks to the distribution of income. The authors use the markedly high differences in the quintile distribution of income, the P90/P10 ratio and, the Gini Coefficient to compare the American distribution to other wealthy countries. All three categories point to poor distribution, which has severely increased over the past few decades. This has sparked a pervading discourse that discusses the magnitude of the issue across the internet, magazines and news sources. But how serious is this issue and what can be done to combat it?

From 1970 to 2012 the top 20% of household’s share of national income increased by 10.1% while the second wealthiest quintile barely moved. Therefore, that 10.1% increase in the wealthiest quintile burdens the lowest three.  The P90/P10 ratio shows that those in the top 90% earn six times as much as those in the lowest tenth percentile. Since 1979 this ratio has increased more dramatically than in other similar countries such as the United Kingdom, Germany, and Canada. Finally, the Gini Coefficient shows once again that in the United States inequality has increased more than in these other wealthy countries. The United States’ coefficient has increased to .394 while that of many other countries has decreased. These number all point to this issue becoming worse and worse, and more rapidly than other wealthy countries. However, these numbers do not expressly point to a definitive change in the quality of life of these groups.

Some criticize how severe this issue truly is. Perhaps the income distribution appears worse from these statistics than it truly is. These three mentioned statistics measure income, and not wealth, which could more accurately measure the change in quality of life between the distribution. Other critics say that the everyone is better off, the statistics just state the increase has been more modest for the lower classes. Additionally, the capitalist cycle fluctuates over time which could lead to a natural reduction in the future.

If the issue is as alarming as it is often portrayed, then the government should use policy changes to shorten the income gap. Potentially, the government could further invest in education, allowing more fluidity between classes and push more people to higher incomes. In addition, the government could continue to increase the minimum wage. Moreover, another option would be to make taxes more progressive, which could generate revenue to be used for greater redistribution of wealth.  These could potentially work to shorten the gap and generate revenue back in the disappearing middle classes.
