Tourism and business travels would probably take a hit.
Some would still come, but much less. I personally have chosen to avoid travel in USA during trump 1. I would again if things get crazy. I know that Australia, for instance, lists USA as risky for gun violence and demonstrations. It particularly calls out election and inauguration as to be avoided. It’s still noted as safe, but not as safe as Australia due to general violent crime. https://www.smartraveller.gov.au/destinations/americas/united-states-america
The American brand still has a lot of value and a lot of American exports are tied to that brand. A large part of that brand is Freedom™. If the USA were to go full fascist, that brand is fucked.
There is also the idea that part of America’s media strength is based on a free market for cultural output. A fascist America would likely not have the ability to pump out the quality of media that it did before due to government censors.
I think the strongest brand America has ever had is capitalism™. And I don’t think anything would change in the entertainment industry if America was openly autocratic. I think the US is organized that way for a very long time, just with a veneer of democracy to keep the people somewhat happy.
