America already has the most progressive tax system in the developed world.
As budget deficits surge toward the stratosphere, Congress will soon have to get serious about savings proposals. Yet reforming Social Security and Medicare—the leading drivers of long-term deficits—remains a political nonstarter. Neither party is willing to raise middle-class taxes. And cutting defense and social spending would save at most $200 billion annually from deficits that are projected to approach $3 trillion by 2034.
That leaves one option: Tax the rich. It won’t be nearly enough.
There are a few excessive tax loopholes and undertaxed corporations that lawmakers could address. It’s farcical, however, to suggest that the tax-the-rich pot of gold is large enough to rein in our deficits and finance new spending programs. Seizing every dollar of income earned over $500,000 wouldn’t balance the budget. Liquidating every dollar of billionaire wealth would fund the federal government for only nine months.
In a study for the Manhattan Institute, I set upper-income tax rates at their revenue-maximizing level, while paring back tax loopholes and fighting tax evasion. As background, the Congressional Budget Office projects that our budget deficits—which currently exceed 7% of gross domestic project—will surpass 10% of GDP over the next three decades. My research shows that the “tax the rich” model would raise at most 2% of GDP in additional revenue over the long term.
