Phil Gramm and John F. Early write in The Wall Street Journal The Truth About Income Inequality
In all, leaving out taxes and most transfers overstates inequality by more than 300%, as measured by the ratio of the top quintile’s income to the bottom quintile’s. More than 80% of all taxes are paid by the top two quintiles, and more than 70% of all government transfer payments go to the bottom two quintiles.
America’s system of data collection is among the most sophisticated in the world, but the Census Bureau’s decision not to count taxes as lost income and transfers as gained income grossly distorts its measure of the income distribution. As a result, the raging national debate over income inequality, the outcome of which could alter the foundations of our economic and political system, is based on faulty information.
Today government redistributes sufficient resources to elevate the average household in the bottom quintile to a net income, after transfers and taxes, of $50,901—well within the range of American middle-class earnings. The average household in the second quintile is only slightly better off than the average bottom-quintile household. The average second-quintile household receives only 9.4% more, even though it earns more than six times as much income, it has more than twice the proportion of its prime working-age individuals employed, and they work twice as many hours a week on average. The average middle-income household is only 32% better off than the average bottom-quintile households despite earning more than 13 times as much, having 2.5 times as many of prime working-age individuals employed and working more than twice as many hours a week.
Antipoverty spending in the past 50 years has not only raised most of the households in the bottom quintile of earners into the middle class, but has also induced many low-income earners to stop working. In 1967, when funding for the War on Poverty started to flow, almost 70% of prime working-age adults in bottom-quintile households were employed. Over the next 50 years, that share fell to 36%. The second quintile, which historically had the highest labor-force participation rate among prime work-age adults, saw its labor-force participation rate fall from 90% to 85%, while the top three income quintiles all increased their work effort.
This blog has several posts on the misleading measurement of inequality. You can search them in the archives.
Inequality is difficult to measure. Measuring consumption power is clearer. Furthermore whether you are measuring households or individuals, whether you account for hours worked, and what time period you are measuring all have material impact on the conclusion. Too often these parameters are manipulated to mislead, and the resulting headline is all that is remembered.
Relative poverty is a very different problem from absolute poverty. If you were sitting in a room with a 100 executives making a six figure income and Bill Gates walked in, the inequality would skyrocket. Is that a problem?
