It’s way, way more than that. Specialization and comparative advantage underpins the entire globalized economy which is the only way to allow us to get more for the same amount of labor. Without it, we simply regress. US farmers grow soybeans so that Chinese manufactures can make the tractors to allow the US farmers to grow the soybeans, and that only works with free trade. And in this scenario there is no one else making a tractor for anywhere near the same cost, and no one else who can grow such a large volume of soybeans, otherwise the trade probably wouldn’t be happening in the first place. And so the alternative is that both countries have to make both independently. And that is more expensive without the efficiencies of economy of scale, more expensive because of lower supply because we don’t have the capacity to produce that many tractors and China can’t grow that many soybeans, and more expensive because of the infrastructure costs being duplicated and spread out over less units. And so we both end up with less tractors and less food that are more expensive. Now add in petrochemical fertilizers imported from Canada, steel and coal for the metal used in the tractor imported from Australia, all the industries that support them also getting caught into this, and where every one of those companies is tied into their regional, national, and the global economy. And that is just for tractors and soybeans.

We trade for almost everything. And every single item that we trade, we do so because it is cheaper than making it ourselves. Tariffs are an artificial tax on efficiency, and we are literally less prosperous with them in place. Some things are a matter of national security, of not allowing a foreign government leverage over your society, but we’re talking about his genius plan to put tariffs on literally fucking everything - soybeans and tractors, but also clothing, toys, electronics, appliances, vehicles, on and on and on. And a tariff on it will increase the price, because that is just how economics works.
