So, Trump’s tariffs are out. He claims they’re half of what each country tariffs the US, but in fact they appear to have been determined by dividing how much the US sells to a country by how much that country sells to the US.
In other words, the more your trade surplus is, proportionally, the higher the tariffs.
This isn’t, on the face of it, necessarily stupid. But… it’s being done very stupidly.
The first problem is the most fundamental: much of what the US buys it can’t make or grow or dig up itself. New capacity takes time, so in cases where the US could in theory make whatever it is, tariffs should either be phased in, or there should be a delay “in two years the tariff will be X%.” As it stands, in a lot of cases, all this is going to do is make Americans pay a lot more.
