Let me try an actress analogy for tariffs.

American production company MGM signs several B-list actresses to act in movies. All American born, beautiful, talented, all those movies are successes for the studio and for audiences to enjoy. Then, a couple of them turn A-list (your Joan Crawfords, Bette Davis's).
Suddenly, MGM decides to outsource talent, not even from Europe, but from some third world country and create lower quality entertainment that is cheaper and arguably more profitable, but those homegrown actresses are likely to be without reliable work. Even worse, MGM has the audacity to sell said smut to American audiences at double the cost and collect all the royalties/profit.
You issue a tariff to MGM that says, " you want to sell all this stuff from overseas, fine, but we're taxing you for not being domestic and hoarding all that money." Now, MGM has to pay or just rehire domestically for entertainment. It'll cost more short term, but long term, those profits could be made back from the American consumer through employment or profit.
Even better, other countries may want a taste of whatever you're making. Who wouldn't want to see Joan Crawford serenade the audience with her drop-dead gorgeous composition, stellar acting, and confident demeanor? Then, MGM could have a premium fee for translation, distribution and exposure. Maybe even offer trade for foreign movies that Americans could enjoy.
