If "the economy" is going to be fixed, first Congress and the senate will actually have to start passing bills again, but that's probably not happening for another decade
The economy is about to become the only 2020-era talking point left. The only Congressional action will be a national abortion ban, which is simply and anticlimactically saying that abortions will be moved to Canada. And the popular vote in this election proves no widespread Democratic party vote tampering. So there will be a day, sometime in 2025, when a critical mass of Trump supporters need to ask, "Who is this Elon Musk guy who I didn't vote for?"
