I think the reality is, many Americans "feel" like they have been in a recession for a while now, even if the economic numbers don't show it. Since the pandemic, there has been a K-shaped recovery - the people who were able to work from home and keep their jobs saved a bunch of money, were able to invest to hedge some inflation, and came out in a better spot. Those who weren't able to work and lost paychecks barely scaped by, and have been hammered by inflation. This has led to 50% of spending in America being done by the top 10% of the population.
Many of Trump's policies are aimed at bringing back value added low to medium skill work in the US (while deporting non-American low skill works and getting rid of government jobs that do not efficiently add value) that should, in theory, strength the economic power of that group in the long run. There is just a gap between when the negative effects hit (i.e. tariffs), and when the positives happen (i.e. new manufacturing plants are up and running). There's also the extra hesitancy from companies that need to invest that all this can be undone by the next President before we ever get to the positives, so the earlier he does all this, the better chance the positives happen and stick before someone comes in after him and undoes it all. If you trigger a recession in the short term - so be it. Recessions are a natural part of the business cycle and we're due for one anyways.
Ideally, you'd want to do this a little more strategically, but our 2-4 year political cycles don't make that possible, so you have to go a little more slash and burn, ask for forgiveness vs permission, to make any changes that actually last.
At least, that's my view of how he's looking at it. There are geopolitical implications as well in brining more manufacturing capability to America.
