Broad tariffs are objectively and absolutely garbage, but these are the most likely to occur, sadly.
Tearing down "all the agencies" may sound scary but I don't know that all the GOP senators are going to throw out their pork programs, same with gutting domestic military spending. Gutting foreign military aid, and letting foreign oppressive regimes run unchecked, that's a real possibility. Gutting consumer protection agencies, that's a possibility (depending on how many people those agencies employ, of course.)
Enforcing immigration is also likely to occur, and this will also be a net negative for society. This costs a lot, yes, but the benefits are greater.
Less corporate tax and likely much less antitrust enforcement... this is going to drive the wealth divide. We'll also have record deficits, because although the GOP likes to cut taxes, they don't cut spending enough either.
Climate stuff - the effects are so far off, that we're probably going to see this going in the wrong direction, because "who cares about future generations, when I have to sacrifice some small luxuries today?"
Health Care: repealing ACA will not do anything good, but so many people are still upset that ACA didn't actually bring healthcare costs down, that they want ACA gone just out of spite I think.
My forecast: we're going to get a recession, and there's going to be even worse military action in one or all of Europe, the Mideast, or Taiwan. Foreign relations will deteriorate further because we basically can't be taken seriously any more. We'll deport a bunch of people, but everyone will still scream that all the Bad Things like the recession are due to DEI and "foreigners" and if we just had stronger borders and were allowed to publicly mistreat people we think are weak/different, we'd be fine. We'll keep falling behind in technology and manufacturing because we've now shifted from a "let's do it!" culture to a "who can we blame?" culture. This is the worst part of the Trump cult: only He can save us, everyone else is at fault, and if you don't think He can fix it, you're "the evil within."
