Yea, inflation sucks. But it's not like Trump can fix the fact way too much money was printed during COVID crisis. The crisis should have resulted in a major economic depression, but instead we got a big party through stimulus. Now we're suffering from a hangover, and Trump can't change that.
Trump can absolutely reign things in, I don't think anyone thinks he can snap his fingers and 'fix' something broken this badly.
But yeah, he 100% can take a different direction than the administration that printed more USD than had previously existed in the entirety of the countries history.
'Trump can't wave a magic wand and un-do what the current admin did, so it doesn't make sense to change directions best to stick with the current administration that doesn't think there is anything they could or should have done different' is not the rationale for my position.
Just look at how the stock market responded today - clearly I'm not the only person who thinks 'this will position our economy much better than it is today'.
