If you remove Trump from the equation you have to go to pre-1913 USA when most of US revenue came from high tariffs on imports.
That’s easy to find. And you’ll find things about high tariffs preceding the Great Depression.
I’m trying to find something MODERN, 1950-2024.
But if you want analysis of pre-1913 policies and what is the same and different between then and now, that’s also possible to find and can eliminate the Trump name from things.
