Like all candidates for the presidency, Donald Trump made a number of rather bold and likely fanciful claims that he would restore prosperous times to the U.S., even going so far as to say that we should expect the return of sustained 3.5 to 4% (or even higher!) rates of year-over-year GDP growth.
But I believe he's going to have a very difficult time of it.
It's obvious enough that we need serious reform in a number of areas. First, our tax code, especially the corporate tax, is in serious need of a do-over. In fact, many analysts consider our corporate tax system the worst in the advanced world. Even Jason Furman, way back in 2007, rendered that opinion. Yet his boss was M.I.A. on that issue to an extent equal to his predecessors.
Second, there's little doubt that our clusterfuck of a regulatory thicket is an impediment to growth. Real reform is obviously needed in that area as well.
Third, our ever-bloating debt burden is a restraint to growth. John Mauldin recently reminded readers that we also have to take into account state and local level public debt to get the real picture, and estimates that the total (federal, state, local) debt is now well over 120% of GDP. Reinhart and Rogoff have written that when a nation's public debt burden passes 60% by a significant margin, it acts as a lasting impediment to growth.
Conservative commentators such as Steve Forbes, Stephen Moore, and Larry Kudlow have often opined that if we were to re-run the Reagan playbook," we could restore the growth rates of the early-to-mid '80s or the last half of the '90s.
Not a chance, in my opinion.
Today's economy does not resemble that of 1981 at all. For starters, inflation and interest rates were through the roof at that time. Once the Federal Reserve under Volcker did what needed to be done and crushed the back of inflation, the economy was teed up nicely for a powerful cyclical recovery. Also, the debt/GDP ratio was only a little over 30%, so we had the fiscal space within which to cut taxes significantly and also increase spending, which of course we did. I'm not arguing that it was necessarily good to run the post-1981 deficits that we did; only that we had the fiscal space within which to do so, as there was still an economically non-destructive path back to fiscal sustainability. (The debt/GDP ratio at the end of the '80s was still about 50%.)
But now we are not remotely in the same situation.
For starters, the debt/GDP ratio is double what is was in 1989, and even more than that if you add in state and local debt. Further, there's no credible path to fiscal sustainability even if we leave most current policy in place, let alone if we pass large tax cuts, a large infrastructure spending surge, and increase defense spending. Doing all that would likely add $10 trillion more to the federal debt by sometime in the early 2020s. Would that precipitate a catastrophic crisis at some point during the next few years? I have a feeling we are going to find out.
Further, high rates of economic growth are likely not to be in the cards, no matter what we do on the policy front. Economic growth is a function of increases in total factor productivity and the size of the workforce. For reasons that are widely debated, but far from completely known, productivity gains have slowed to a crawl since around 2004. We need a fresh new round of technological advancement. It's been pointed out by many analysts that innovations of the last decade or so, while fun and interesting, are not economically transformative in the ways that earlier advances were.
Although I think that good tax reform and well-done regulatory relief are unambiguously good things, I'm still afraid we are going to be in for a slow-growth slog for years to come. I suspect that this may present very difficult challenges for Trump and the Republican congressional majority.
We have certainly seen many markers of great optimism, especially since the U.S. stock market has taken a very nice ride all the way into the high 2300s, but I'm afraid that level of exuberance in unwarranted.
