I'm not American but tariffs might be a way to "make America great again" because it makes it harder to trade with other countries. This means that it makes it relatively easier than before, to trade within the USA.
Another effect is that it serves as a tax. Easy for me to say but I think Americans aren't taxed enough.
What I find so astonishing about this recent US "debate" is that I was taught in my German high school during the 1980s in a discipline called "Erdkunde" that the US is transitioning from a manufacturing to a service-oriented economy that would be vastly superior to the classical manufacturing-based approach and that Germany would need to make this transition, too, if we wanted to remain globally competitive.
I don't want to glorify German high schools but I find it hard to believe that those school books were so wrong that 40 years later it would make sense to return to a manufacturing-oriented economy.
I don't "like" taxes I just think that people are more generous when they are obliged to be. It won't make them generous on top of the taxes but at least they'll pay the damn taxes.
I live in France where the taxes are much higher than in the US. It's annoying but there are clearly some advantages and we are adapted to a more humble lifestyle, which is fine.
