I think that "the economy" is both too complicated and too meaningless of a concept for anyone to actually understand, so people just absorb vibes from the media. The idea that a good economy is one where you, personally, are prosperous is pretty foreign. So very little will change for most trump supporters but by next summer they will be totally convinced that the economy is better that it has ever been.
Uh unless they actually dissolve the federal reserve and go back to the gold standard like it apparently says in project 2025. In that case it will literally cause the collapse of the US empire.
I recently got my passport changed. It was pretty easy besides being a bit expensive, I just bought all of the documents to a post office and had my new one in like 3 weeks.
I did have the court order, not sure if it can be done without. You could probably use your old birth certificate, the point of that is just to establish citizenship. Tho IMO you should change your birth certificate if your state makes it easy, it will potentially help avoid headaches in the future.
