How Trump Can Achieve Sustained 3% GDP Growth

The incoming Trump administration has set a goal of growing the economy by 3% per year, similar to promises made during Donald Trump’s first term in office. In a sense, it’s an easy goal to achieve quickly because we already have. Real gross domestic product has expanded by more than 2.5% on an annualized basis in eight of the past nine quarters through Sept. 30, and the average among those eight quarters has been … wait for it … 3.1%! We won’t get official numbers for the fourth quarter for a few weeks, but the latest tracking estimates are around 2.45%.

The real question is whether the US can achieve sustainable 3% growth over the long haul. That’s much harder, but the benefits of strong economic growth are enough that it’s worth indulging in the idea.

Most economists peg our “potential” real GDP growth at roughly 2% a year. Potential growth is affected by several things, including the labor force (which in turn reflects aging, fertility and immigration), productivity, educational and skills attainment, and technological change. While the consensus around 2% is strong, potential growth is unobservable and based entirely on models. So, the consensus could be wrong, especially if the economy is undergoing structural changes that are hard to measure in real time.

Boosting potential growth by an extra percentage point to 3% for a decade may sound trivial, but economic superpowers are built on such differences over time. In 1896, Argentina was one of the world’s richest nations. Its GDP per capita was 83% of the US’s, higher than France and Germany at the time, according to Maddison Project data. Since then, growth in real Argentine GDP per capita has averaged 0.9% annually, versus 1.7% in the US. After more than a century of that seemingly small wedge, Argentine GDP per capita is less than a third of the US.

Three percent growth in the US has been the norm going back to the country’s founding in the late 1700s. But the past often saw faster population growth than now, from both higher sustained fertility and immigration. In the chart below, the orange line shows what historical GDP growth would have looked like with 2023’s population growth. As you see, 3% growth becomes a rarity, and would be even rarer with slower population growth than 2023, say from aging or lower immigration.
