However, those who argued that the tax cuts would “pay for themselves” always misunderstood the Laffer Curve. Tax cuts — at least some kinds of supply-side tax cuts — can generate additional economic growth, which means that those cuts seldom result in a dollar-for-dollar revenue loss. But that doesn’t mean they are a completely free lunch.
Given stagnant labor-force-participation rates and slowing population growth (caused in part by the president’s anti-immigration-policies), the Trump administration was essentially assuming that the US economy would experience a productivity boom larger than any in post-war history. It hasn’t happened. The Trump tax cuts are estimated to have reduced federal revenues by roughly $230 billion already, and by $2.3 trillion over ten years.
That would be perfectly fine if we simultaneously reduced federal spending. As Milton Friedman pointed out, the true cost of government is not found in taxes or debt, but in spending. Taxes and borrowing are just alternative ways of paying the cost. A smaller, less costly, less intrusive government would be better for all of us, would generate more growth, and would require fewer taxes to pay for it.
Yet Donald Trump is on track to be an even bigger spender than Obama. Federal spending has increased by 7.5 percent, or almost $300 billion, over President Trump’s first couple of years in office. Conservatives might applaud the over 8 percent increase in defense spending, although that increase seems unrelated to any strategic plan or external threat. But what should Republicans make of the 7 percent increase in domestic spending?
One expects this sort of fiscal insanity from congressional Democrats. The party that already favored “health care for all,” “college for all,” and “jobs for all” recently began a push for “housing for all.” As a down payment, Senator Kamala Harris (an expected 2020 presidential candidate) is calling for billions in federal rent subsidies that would primarily benefit Californians facing the consequences of their own irresponsible zoning regulations. Their 2020 slogan might as well be “everything for everyone.”
Republicans used to be different. No longer. As Rep. Justin Amash (R., Mich.) recently tweeted:
Worse, there is no sign that either the Trump administration or congressional Republicans get it. The Trump administration continues to rely on growth projections that are considerably higher than those of the Congressional Budget Office or independent analysts. The administration also ignores warnings that the trade war it is pursuing could reduce U.S. GDP by hundreds of billions of dollars per year. Nor does the administration consider that the increase in debt will itself reduce economic growth.
And the administration continues to spend money with reckless abandon. Recently, for example, the president suggested a fund to pay farmers for the losses caused by the president's trade policies. Entitlement reform remains entirely off the table.
President Trump's supporters like to point out that he does things differently than previous presidents. No doubt. Unfortunately, however, when it comes to big spending and fiscal irresponsibility, President Trump is as conventional as they come.
