Trump’s deficit-busting tax cuts and increases in government spending make no sense for an economy with an unemployment rate of 3.8 percent
NEW HAVEN – With each passing day, it becomes increasingly evident that US President Donald Trump’s administration cares less about economics and more about the aggressive exercise of political power. This is obviously a source of enormous frustration for those of us who practice the art and science of economics. But by now, the verdict is self-evident: Trump and his team continue to flaunt virtually every principle of conventional economics.
Trade policy is an obvious and essential case in point. Showing no appreciation of the time-honored linkage between trade deficits and macroeconomic saving-investment imbalances, the president continues to fixate on bilateral solutions to a multilateral problem—in effect, blaming China for America’s merchandise trade deficits with 102 countries. Similarly, his refusal to sign the recent G7 communiqué was couched in the claim that the US is like a “piggy bank that everybody is robbing” through unfair trading practices. But piggy banks are for saving, and in the first quarter of this year, America’s net domestic saving rate was just 1.5 percent of national income. Not much to rob there!
The same can be said of fiscal policy. Trump’s deficit-busting tax cuts and increases in government spending make no sense for an economy nearing a business-cycle peak and with an unemployment rate of 3.8 percent. Moreover, the feedback loop through the saving channel only exacerbates the very trade problems that Trump claims to be solving. With the Congressional Budget Office projecting that federal budget deficits will average 4.2 percent of GDP from now until 2023, domestic saving will come under further pressure, fueling increased demand for surplus saving from abroad and even bigger trade deficits in order to fill the void. Yet Trump now ups the ante on tariffs—in effect, biting the very hand that feeds the US economy.
So what Trump is doing is not about economics—or at least not about economics as most academics, political leaders, and citizens know it. Sure, Trump has been quick to draw on some fringe mutations of economics—say, Arthur Laffer’s infamous back-of-a-napkin supply-side musings—but none that have withstood the test of time and rigorous empirical validation.
But why single out economics? The same complaint could be made about Trump’s views on climate change, immigration, foreign policy, or even gun control. It’s power politics over fact-based policymaking.
This should not be all that surprising. Trump’s battle with China merely underscores his eagerness—transparent from the start—to use economics as a foil in his pitch to “Make America Great Again.” Contrary to his bluster over unfair trade deficits, China’s real challenge to the United States is less about economics and more about the race for technological and military supremacy.
Indeed, the pendulum of geopolitical leadership is now in motion. China’s massive pan-Asian infrastructure plan, the Belt and Road Initiative, together with its muscular behavior in the South China Sea, pose far greater threats to American hegemony than does one bilateral piece of a much larger multilateral trade deficit. At the same time, China’s recent efforts to build the institutions of an alternative financial architecture—spearheaded by the Asian Infrastructure Investment Bank and the New (BRICS) Development Bank—stand in sharp contrast to an increasingly inward-looking US.
Much has been written about the historical trajectory of great powers and the military conflicts that often arise during their rise and fall. This is where economics eventually comes back into play. Geostrategic power and economic power are joined at the hip. As Yale historian Paul Kennedy has long stressed, a condition of “imperial overreach” arises when the projection of military power outstrips a country’s shaky economic foundations.
It has been 30 years since Kennedy warned that the US, with its excessive defense spending, was increasingly vulnerable to such overreach. But then the would-be heirs to the US faded: The Soviet Union collapsed, Japan’s economic miracle imploded, and Germany became entangled in reunification and European integration. An unthreatened America plodded on.
China, of course, was barely on the radar screen back then. Moreover, in 1988 the US had a net domestic saving rate of 5.6 percent of national income—only slightly below the 6.3 percent average of the final three decades of the twentieth century, but nearly four times the current rate. Back then, the US was spending $270 billion on defense—less than half the $700 billion authorized in the current budget, which now outstrips the combined military outlays of China, Russia, the United Kingdom, India, France, Japan, Saudi Arabia, and Germany.
Meanwhile China has ascended. Back in 1988, its per capita GDP was just 4 percent of the US level (in purchasing-power-parity terms). This year, that ratio is close to 30 percent—nearly an eightfold increase in just three decades.
Can power politics offset the increasingly tenuous fundamentals of a saving-short US economy that continues to account for a disproportionate share of global military spending? Can power politics contain the rise of China and neutralize its commitment to pan-regional integration and globalization?
The Trump administration seems to believe that America has reached a propitious moment in the economic cycle to play the power game. Yet its strategy will succeed only if China capitulates on the core principles of the growth strategy that frames President Xi Jinping’s great power aspirations: indigenous innovation, technological and military supremacy, and pan-regional leadership.
Like Trump, Xi does not do capitulation. Unlike Trump, Xi understands the linkage between economic and geostrategic power. Trump claims that trade wars are easy to win. Not only is he at risk of underestimating his adversary, but he may be even more at risk of over-estimating America’s strength. The trade war may well be an early skirmish in a much tougher battle, during which economics will ultimately trump Trump.
