In 2014, Barack Obama sat in the White House. By that year, the Affordable Care Act — legislation that both increased health benefits for lower-income Americans and increased federal taxes on higher-income Americans — had gone almost fully into effect. But those changes, the new CBO report shows, didn’t turn out to be enough to reverse rising inequality.

U.S. household income, the report documents, remained “unevenly distributed” in 2014, with households at the top of the income distribution receiving “significantly more income than households at the bottom of the distribution.”

How much more significantly? After totaling all varieties of income and government benefits — and subtracting out federal taxes — the CBO researchers found that poorest 20 percent of U.S. households averaged $31,100 in 2014. Households in the top 1 percent of the nation’s 2014 income distribution averaged $1,178,600.

This gap would have been considerably wider without the government benefits the CBO labels “means-tested transfers,” the cash and in-kind services lower-income households receive from programs like Medicaid. In 2014, these programs increased the incomes of the poorest fifth of American households by an average 64 percent.

Overall, the combined impact of transfers and taxes increased the bottom 20 percent 2014 share of U.S. income by over 3 percentage points and decreased the top 20 percent share by almost 7 percentage points.

A sign of egalitarian progress worth applauding? Most certainly. But that progress, after only a year-plus of the Trump administration, has faded. Tax rates on our richest have sunk, as has budget support for basic social benefits.

But in 2014, even with that progress, the divide between America’s rich and everyone else was still widening, continuing the income tilt to the top that the new CBO report tracks back to 1979.

Between 1979 and 2014, after figuring in all taxes and social program transfers, the after-tax incomes of America’s top 1 percent rose over three times faster than average incomes in the bottom 20 percent — and over six times faster than incomes in America’s statistical middle class, those households in the exact middle 20 percent of the nation’s income distribution.

Between 1979 and 2014, these middle class households saw their incomes increase by $9 per week. Top 1 percent households, over the same years, gained on average an extra $450 every week, 50 times more than middle class households — and 64 times more than the $7 dollars per week that average households in the nation’s poorest 20 percent gained.

Middle- and low-income Americans have paid a heavy price for those few extra dollars per week. Their schools have become more overcrowded, their streets more potholed, and their college costs much more expensive as tax giveaways to the rich and powerful shrink the budgets for basic public services.

Average Americans have a right to be upset. Wealthy Americans like Donald Trump have no right to exploit their anger.
