I'd hate to trivialize this by making it seem like not being able to buy old cameras and lenses is the sole effect of this. Right now there is a confluence of stupidity in American politics, that is creating a whirlpool of economic ruin that will last decades... but I'll leave the specifics for some other forum.
The trade deficit spiel is really rather stupid. Just for example, the U.S. has never produced a commercially successful precision 35mm camera. So we put tariffs on cameras. For what reason? Is Leica Camera AG going to leave Germany and build a new factory in the U.S. if we make it harder for them to do business here? If the government artificially shrinks their market, are they going to build cameras for Americans in America? And could that even happen? What if one of Leica engineers or experts shared a meme of JD Vance? Would we bar them from entering the country for having a sense of humor? (apparently freedom of speech is dead, we already see people getting fired left and right for the the pettiest reasons...
the biggest promoter of ending the de minimis exemption got fired because
he attended the wedding of somebody who criticized trump, and no, I'm not joking).
Well who knows, maybe Argus will come back and build a few more C3s.
