During the second Obama term, GDP grew at roughly 2.5 percent per year. Inflation was minimal. Trump ran in 2016 on a promise to use tax cuts and deregulation to increase the growth rate substantially. On its own terms, the huge tax cut was a failure, as it did not result in a significant increase in investment. The tariffs did not bring back manufacturing jobs, either, and the deficit exploded. On a more positive note, the tax cut did, in fact, create a small boom in consumption. On the whole, 2017-2019 saw a very slight increase in the rate of GDP growth from the Obama years. Then came the pandemic, and the economy fell into recession.
The postscript to the pandemic was inflation, which was exacerbated a bit by Biden’s spending. The spending increased growth rates, however, and inflation today is almost normal. GDP growth during the Biden years has been virtually identical to the figure during the Trump years if you toss out the impact of the pandemic on both 2020 (Trump) and 2021 (Biden).
Trump is once again promising a huge increase in growth from tax cuts, deregulation, tariffs, and deportations. Based on the historical record for the first two and common sense for the last two, why would anyone believe that?
