Do Republicans Really Want Tax Cuts?

The coming debate over tax cuts will be a debate about the rich in American society.

The coming debate over tax cuts will be a debate about the rich. “Middle-class tax cut” may be the Washington mantra, but the reality is that any broad-based reduction in personal income taxes, under the current tax code, would redound primarily to the benefit of the wealthy. As the latest IRS data reveals, the top 1 percent of earners pay over 39 percent of personal income tax revenues, while the top 5 percent pay 60 percent; the bottom 50 percent, meanwhile, contribute less than 3 percent of federal income taxes.

This poses a dilemma for the Trump administration and House leadership: Will the new, more populist base of the GOP ultimately support their tax agenda?

The inspiration behind the GOP’s tax plan is Reaganomics. From 70 percent on the eve of Ronald Reagan’s election in 1980, the highest income tax bracket fell to 28 percent after the Tax Reform Act of 1986. The economic dynamism that followed over the next two decades instilled in the Republican policy elite an enduring lesson: Tax cuts are not only politically feasible, they are the key to unlocking growth and innovation.

Particularly vindicated were supply-side economists, who emerged from the academic fringe and sold the Reagan administration on “across-the-board” tax relief. It was a radical move for the time—one that GOP Majority Leader Howard Baker likened to a “riverboat gamble.”

Gamble or not, tax reform paid off. As the country, in January 2000, marked its longest economic expansion in history, supply-side economists Lawrence Kudlow and Stephen Moore could credit marginal rate tax cuts for “unleash[ing] a great wave of entrepreneurial-technological innovation that transformed and restructured the economy.” Supply-siders were encouraged again in 2003 when the Bush administration pushed through upper income tax cuts. As Arthur Laffer and Moore noted in their 2008 book The End of Prosperity, the Bush tax cuts produced within four years 150,000 new jobs per month, $6 trillion of household wealth and a 95 percent increase in the number of millionaires.

So even in a populist moment, supply-side insights carried the day as Republicans formulated their tax plans heading into the 2016 elections. Trump has turned not only to Laffer, Kudlow and Moore, but also to a cabinet of wealthy executives who, like he, embody the capitalist success that the Reagan and Bush tax cuts fostered. The House leadership, likewise, developed its plan with the explicit intent to “replicate and build upon [Reagan’s] achievement.”

Ultimately, Trump and the House GOP reached similar policy conclusions. Both plans call for a flatter tax code in which the top income tax bracket is reduced from 39.6 to 33 percent and high-income taxpayers enjoy the largest cuts.

Reaganomics’ legacy may legitimate the economic case for upper-income tax cuts. But they leave unanswered the political question that the Republican leadership must consider before pursuing another wave of tax relief: Why, despite seeing the virtues of a low-tax society, have Republican voters tolerated a steady increase in taxes since the late 1980s? Barely three years after the Reagan tax cuts came into effect, Reagan’s Republican successor reneged on his “no new taxes” pledge, hiking the upper income bracket to 31 percent. Republican House Minority leader Newt Gingrich railed against this “supreme act of stupidity,” but the American people were more amenable—even in the immediate aftermath of the tax hike, 77 percent of the country agreed that “upper-income people” were paying “too little” in federal taxes. Republicans took control of Congress in 1994 on a pledge to cut taxes, but the upper income tax rate has never since dropped below 35 percent.

The answer lays in the evolution of the political coalition that made Reagan-era tax reform possible in the first place. Supply-side economists provided the intellectual framework for tax reform, but their ascent is intertwined with the broader realignment of the Republican Party.
