Why it (sort of) makes sense for the US to impose tariffs

Nearly everyone wonders, “Why is Donald Trump crazy enough to impose tariffs on imports from other countries? How could this possibly make sense?”

As long as the world economy is growing rapidly, it makes sense for countries to cooperate with each other. With the use of cooperation, scarce resources can become part of supply lines that allow the production of complex goods, such as computers, requiring materials from around the world. The downsides of cooperation include:

(a) The use of more oil to transport goods around the world;

(b) The more rapid exhaustion of resources of all kinds around the world; and

(c) Growing wage disparity as workers from high-wage countries compete more directly with workers from low-wages countries.

These issues can be tolerated as long as the world economy is growing fast enough. As the saying goes, “A rising tide lifts all boats.”

In this post, I will explain what is going wrong and how Donald Trump’s actions fit in with the situation we are facing. Strangely enough, there is a physics aspect to what is happening, even though it is likely that Donald Trump and the voters who elected him would probably not recognize this. In fact, the world economy seems to be on the cusp of a shrinking-back event, with or without the tariffs. Adding tariffs is an indirect way of allowing the US to obtain a better position in the new, shrunken economy, if this is really possible.

The upcoming shrinking-back event is the result of too little energy consumption in relation to total world population. Most researchers have completely missed the possibility that energy limits could manifest themselves as excessive wage disparity. In fact, they have tended to assume that energy limits would manifest themselves as high energy prices, especially for oil.

The world’s networked economy doesn’t work in the simple way that most researchers have assumed. Too much wage disparity tends to lead to low energy prices, rather than high, because of increasing affordability issues. The result is energy prices that are too low for producers, rather than too high for consumers. Producers (such as OPEC nations) willingly cut back on production in an attempt to get prices back up. The resulting shortage can be expected to more closely resemble financial collapse than high prices and a need for rationing. Trump’s tariffs may provide the US a better position, if the world economy should partially collapse.

Let me try to explain some pieces of this story. Continue reading
