End Bush cuts for wealthiest Americans; extend them for everyone else.

The economic crisis four years ago hit the American middle class as it was already reeling from three decades of stagnant wage growth.

OUR VIEW: Taxes debate avoids hard truths

The worst was yet to come. The Great Recession saw poverty soar, home values plummet and retirement savings sharply decline. It's little wonder that the Pew Research Center labeled the 2000s the worst decade for the American middle class in modern history.

All the while, income inequality worsened. By 2010, 93% of income growth went to the top 1% of Americans.

It is within that unsettling reality that we confront the fiscal problems before us and debate the merits of extending tax cuts for middle- and lower-income Americans while ending them for the very wealthy.

The question we face is not whether the highest earners should bear the entire burden of deficit reduction, but rather whether they should play an important contributing role. The answer, overwhelmingly, is yes.

While middle-class wages stalled over the past 30 years — in 2011, half of American workers earned less than $26,965 — the very wealthy prospered. Incomes of the top 1% of Americans have nearly tripled, even after accounting for inflation, since the late 1970s.

The Bush tax cuts only worsened the divide, helping to reduce overall taxes paid by the wealthiest 1% by 7 percentage points between 1980 and 2010. The Congressional Research Service, in a recent report, concluded: "As the top tax rates are reduced, the share of income accruing to the top of the income distribution increases."

Middle- and lower-income Americans have been bearing the brunt of our nation's economic malaise, and fiscal condition, for years. No one is suggesting that dealing with the deficit won't require contributions from all Americans. But it is essential that in grappling with the "fiscal cliff," and beyond, we keep in mind the challenges confronted by the American middle class in recent decades and the unprecedented prosperity enjoyed by a very small minority at the top.

We must end the tax cuts for those at the very top and extend them for everyone else.
