The Inequality Myth

Excerpt:

Class warfare is once again a campaign theme. The Democratic candidates are railing against the "tax cuts for the rich," lamenting the stagnation of middle-class incomes, and decrying the deepening woes of the poor. In her January response to President Bush's State of the Union address, Hillary Clinton cited "seven years of stagnant wages, declining incomes and increasing inequality." Barack Obama echoes this theme by referring repeatedly to the "middle-class squeeze."

First, we can easily dismiss the notion that the poor are getting poorer. All the Census Bureau tells us is that the share of the pie consumed by the poor has been shrinking (to 3.4% in 2006 from 4.1% in 1970). But the "pie" has grown enormously. This year's real GDP of $14 trillion is three times that of 1970. So the absolute size of the slice received by the bottom 20% has increased to $476 billion from $181 billion. Allowing for population growth shows that the average income of people at the bottom of the income distribution has risen 36%. They're not rich, but they're certainly not poorer. In reality, economic growth has raised incomes across the board.

Since 1970 there has been a dramatic rise in divorced, never-married and single-person households. Back in 1970, the married Ozzie and Harriet family was the norm: 71% of all U.S. households were two-parent families. Now the ratio is only 51%. In the process of this social revolution, the average household size has shrunk to 2.57 persons from 3.14 -- a drop of 18%. The meaning? Even a "stagnant" average household income implies a higher standard of living for the average household member. Last year, the Census Bureau published a new set of income statistics that adjusted for changing household size and composition. In a single year (2006), this "equivalence-adjusted" computation increased the income share of the poor by 8% and reduced the standard measure of inequality (Gini coefficient) by 4%. Such "equivalency" adjustments would mute unadjusted inequality trends even more.

The supposed decline of the poor and middle class is exaggerated even more by the dynamics of population growth. When people look at the "poor" in any two years, they think they're looking at the same people. That's rarely true, especially over longer periods of time. Since 1998, the U.S. population has increased by over 20 million. Nearly half of that growth has come from immigration, legal and illegal. Overwhelmingly, these immigrants enter at the lowest rungs on the income ladder. Statistically, this immigrant surge not only reduces the income of the "average" household, but also changes the occupants of the lowest income classes.

To understand what's happening here, envision a line of people queued up for March Madness tickets. Individuals move up the line as tickets are purchased. But new people keep coming. So the line never gets shorter, even though individuals are advancing. Something similar happens with the distribution of income. People keep entering the distribution line from the bottom. Even though individuals are moving up the line, the middle of the line never seems to move. Hence, an unchanged -- or even receding -- median marker could co-exist with individual advancement. The people who were at the middle marker before have moved up the distribution line. This is the kind of income mobility that has long characterized U.S. income dynamics.

When you look at the really big picture, it's apparent that living standards are rising across the entire spectrum of incomes. Just since 2000, GDP has risen by 18% while the population has grown by 6%. So per capita incomes have clearly been rising. The growth of per capita income since 1980 or 1970 has simply been spectacular.

Some people would have you believe that all of this added income was funneled to the rich. But the math doesn't work out. The increase in nominal GDP since 2000 amounts to over $4 trillion annually. If you assume that all that money went to the wealthiest 10% of U.S. households, that bonanza would come to a whopping $350,000 per household. Yet according to the Census Bureau, the top 10% of households has an average income of $200,000 or so. The implied bonanza is so absurd that the notion that only the rich have gained from the economic growth can be dismissed out of hand.
