The next thing the US needs is for Americans to actually buy made-in-America cars. The cars will be higher priced, and fewer will be made, but if nobody buys them then Ford and GM go out of business and the Big Bully Experiment is a flop.

I'd like to see it work, but there are so many moving parts, literally, in global trade and manufacturing. To get Americans to buy US cars, Trump will have to impose import duties on foreign cars. Then the price of all cars will increase. And then all the foreign countries importing US goods will slap retaliatory sanctions and tariffs on their imports, and other tariffs and constraints on the components and raw materials that US manufacturers need.

Or maybe Trump thinks that you can get free raw materials while you impose tariffs on finished goods. Or maybe Trump thinks that car-making robots will buy the now more expensive domestic cars. Who knows what he thinks, or if he even does?
