America's staggering inequality and our strong preference for a Swedish alternative

Most Americans realize that the United States has become more unequal over the past three decades or so. But it's unlikely that most Americans have a full grasp of the sheer magnitude of the change in the distribution of wealth since the end of the 1970s, or its impact on the lives of ordinary Americans.

Many data point to what the political scientists Jacob Hacker and Paul Pierson, in their important new book, Winner Take-All Politics, call "trickle up" economics. For example, according to the Congressional Budget Office, via Lane Kenworthy, the lowest twenty percent of households in America saw their post-tax wages increase from $15,500 in 1979 to $17,500 in 2007 (in constant, inflation- adjusted dollars). The middle sixty percent saw their incomes increase from $44,000 to $57,000 during that period. And the top one percent saw their post-tax incomes explode from $350,000 to $1.3 million, a near quadrupling. The increases for the top one-tenth of one percent and top-hundredth of one percent were greater still.

Of course, many think inequality is irrelevant, as long as a rising tide lifts all boats. But while the wealthiest Americans live ever more opulent lifestyles, ordinary Americans, especially at the sixtieth percentile and below are running in place, if not falling further behind. For one thing, the typical household puts in longer work hours now than was true in 1979, placing added strains on many American families. Furthermore, in the past three years the general picture of distribution has likely worsened, with record levels of long-term unemployment as well as draconian cuts to basic services like health care and education at the state and local level, which have disproportionately affected people lower down the income ladder. So, the relatively weak gains for the majority of Americans in the past thirty years have been precarious, subject to a swift and un-nerving reversal of fortune, while those at the top continue to enjoy record incomes and wealth.

And the growing concentration of wealth at the top is arguably directly related to that growing precariousness for most of the rest of us. Had the pattern of wealth distribution that existed in the 1970s held steady over the subsequent decades, Hacker and Pierson estimate that the lowest sixty percent of households would have enjoyed incomes between $6,000 and $12,000 higher in 2006 than they actually were. That'd be a nice cushion to have in the face of an economic downturn.
