What one thing could we do to best boost future economic growth?

In my article for a Cato Symposium I cite foreign policy:

It is possible that we are still living inside the biggest bubble of them all and that is called “the peace bubble.” I’ve also heard this described as the bubble of “Pax Americana,” although that is a more partisan take on the role of America in global peace. You might think the chance of this being a “peace bubble” is say only five or ten percent. Maybe so, but still in expected value terms that is still the most important issue to worry about. The breaking of that peace bubble on a larger scale could endanger all of the progress and accumulated well-being of the human race, including the United States.

Let’s not forget that over the next one hundred years, if the world remains relatively peaceful, it is unlikely that most global innovation will come from the United States. China in particular may assume a major role as a generator of new ideas, just as the United States supplied a wide variety of useful innovations to Great Britain starting in the mid to late 19th century. Even if a “Fortress America” could survive geopolitical turmoil in the broader world, it would be a much poorer place. We rely on the rest of the world for inspiration, for creation, for appreciation, for increasing market size and thus the spurring of American innovations, and of course we rely on the rest of the world for innovations more directly. A future America in a chaotic world is much, much poorer and riskier than a future America in a peaceful world.

I should note that I am indebted to John Nye and Garry Kasparov for this notion of Pax Americana as the biggest bubble of them all.  There are several other arguments in the piece, for instance:

When electing a President or a Congress, foreign policy should be by far our number one concern. That said, I don’t think there is any simple formula for getting foreign policy right. Unlike many libertarians, I do not adhere to a strictly non-interventionist stance on foreign policy. I believe in alliances among the world’s relatively free and (one hopes) peaceful nations. I believe that American intervention has at some critical times led to much greater freedom and prosperity. Without the current and past American security umbrella, for instance, I believe much of Asia would be a far less free place than it is today, starting but not ending with Taiwan and South Korea.

I am, however, also skeptical of conservative or hawkish claims that we simply need to get tough with the bad guys in the world. A market-oriented economist, as I view myself, should be well aware of the general arguments about the difficulty of government planning and the importance of unforeseen, unintended consequences from government action. Furthermore government policies, once they get underway, are often hijacked by special interest groups or by voters who are uninformed, misinformed, or who react emotionally rather than analytically. We should not be especially optimistic about the ability of our government to pull off successful foreign interventions.

Daniel Larison comments on me here (when I write “For better or worse,” that means I am not judging a possible Syria intervention, contra Larison.  Otherwise the popularity of drones is a good example of American squeamishness, another example being our early withdrawal from Iraq.)  The broader symposium is here, it has many quality contributors.  Here is Eli Dourado on incentive pay for Congress.

Addendum: Arnold Kling comments.
