Trump's Zero-Sum Notions of Trade and How Far That Falls From The Ideal

In an exchange with my friend Brian Blackwell, we were discussing tariffs. One often-overlooked aspect of this topic is the extent to which the U.S., as a dominant global power—both militarily and economically—could theoretically force trading partners into agreements that disproportionately benefit itself at the expense of other nations. This approach would echo the exploitative dynamics of empires and their colonies, where economic relationships were heavily one-sided.

If you view the world as zero-sum, your goal is straightforward: to take as many of their marbles as possible. But if you adopt a variable-sum perspective, you’d focus on creating arrangements that inspire and enable others to produce even more marbles—or perhaps something entirely new and better.

The first objection to exploitative trade practices is clear: while a monopolist might coerce workers into accepting pay cuts because they lack alternatives, such behavior is widely regarded as amoral. Exploitation—even when driven by power rather than necessity—raises ethical concerns that shouldn't be ignored.

The second objection is subtler but equally compelling. Trade, at its core, is a partnership. If you’re going to engage in trade, wouldn’t you prefer a partner who is prosperous, innovative, creative, and productive—someone capable of generating value comparable to your own? And someone just as excited about your trade arrangement as you are, just as motivated to innovate and profit? Why enter into a trade agreement with 'Dennis the Peasant,' whose only offering is mud? Wouldn't you rather trade with someone rich than someone poor - someone who makes or has great goods and services? A really valuable trade relationship is one where both sides contribute meaningfully, fostering mutual growth and long-term prosperity.
If history teaches us anything, it is that progress emerges from cooperation - from people playing variable-sum rather than zero-sum games and creating wider and wider circles of collaboration and mutual benefit.
