All Other Things

For one semester at the University of Michigan I was an Econ major, but I got hung up on the Latin phrase meaning “all other things being equal,” which kept showing up in every economic model we studied.

When I somewhat rebelliously wrote a paper arguing that in real life all other things never stay equal, my professor was not amused and gave me a D. That was the end of my would-be major in economics.

I understood, of course, the concept of modeling and the need to control for random factors that could affect the outcome, since I’d also been a math major for a minute. But similar concerns about reality’s messiness compared to math’s formulaic purity derailed my academic trajectory in that subject as well. Quod Erat Demonstrandum if you will.

In the end, I found that I was better suited to working with words, so it was journalism for me, which of course is completely obsessed with the real world and all of its messiness. But wouldn’t you know it, the two subjects that have come up over and over again in my journalism career are economics and math.

Both are necessary today when trying to understand what is happening with Trump’s chaotic foreign adventurism. He tries to bully countries he considers weaker, but that will only backfire in the end. He has got both the math and the economics of what he is doing wrong.

His back and forth statements on the Iran War seem to be mainly about controlling the world’s oil. So was his adventurism in Venezuela and his future plan for Cuba. But the damage from his bombings to critical infrastructure in the Middle East will destabilize the energy markets for many months (maybe years) to come.

Meanwhile, his poll numbers continue to plummet.

Of this I am certain: all other things are most definitely not equal out there in the global economy. I may have gotten a D in Econ for telling the truth but Trump gets an F for lying.
