What Trump definitely can be evaluated on is whether he contributed to America being better prepared for a shock and how the country was faring in the years before 2020. This article looks at the administration’s economic performance from this perspective. The more solid the economy, the better prepared individuals are to face a public health and economic shock.
During the first three years of Trump’s presidency, the economy expanded, unemployment and poverty fell, wages increased, taxes were cut, the stock market moved upward, and some reforms of federal regulation were introduced. So far so good.
Yet we need to be careful before offering kudos to the president. His is a powerful office, but his control over the economy is limited. His administration is constrained by the Constitution and the other branches of government. The policies of previous presidents and Congresses helped establish economic trends. The Federal Reserve System has the power to create money, but this does not give it unlimited power over the economy. Finally, the U.S. economy is only 15% of the world economy and the remaining 85%—which the president cannot easily order around—exerts, through trade, a major influence on domestic prosperity.
The “Trump economy” is thus a misnomer. Like any other president, Donald Trump is only partly responsible for what has gone well and gone wrong during his years in office and in the years to come. A president can do more damage to an economy than help it. And three years is a short time to evaluate the consequences of complex policy packages. All these caveats must be kept in mind.
Moreover, judging how an economy is performing—leaving alone the question of who is responsible for that performance—is more difficult than it might seem. The ultimate criterion should be the welfare of all individuals. But welfare is subjective and impossible to measure directly, let alone comparing it between individuals, so real income (measured by gross domestic product) usually is the substitute criterion. In economic punditry and even academia, other metrics are also used, such as employment, investment, and wages.
It is helpful to compare Trump’s first three years to the performance of his immediate predecessor, Barack Obama. The two have much in common: both turned out to be interventionists and many classical liberal or libertarian economists would argue they both did more economic harm than good. Comparing them helps to provide economic and historical context.
