I do know - being a regular visitor, maybe 4-5 times a year, I can confirm that from 2021-24 the price of food went crazy. I even had a couple of interesting convos with my boss at the time to show him my TJ receipts (my travel budget didn't go up so I had to opt for less dining out, only essential business entertaining and apartments instead of hotels). Having said that, I genuinely fail to see how the tariffs are going to help address the cost of living. Some larger importers might be able to absorb some of the customs bills but logically a lot is going to be passed on to the consumers. 100% of the tariffs will be paid in the US, be that by importers and/or consumers.
To your reasons - thanks for sharing, and you have those in common with the Republicans I personally know (because yes, I do know Republicans!). I think the divide is pretty fundamentally about whether you believe the end justifies the means and whether you are happy with the price to pay:
Immigration - sure, the numbers are going down but that comes with talented people worrying about coming to the US, and most crucially, with due process and rule of law being undermined. I am not comfortable with that approach. It's up to US voters to decide, but I see the MAGA influence on Reform making the same proposal to the electorate and I could not subscribe to it, ever.
Staying out of war - again at what cost? Maybe Ukraine is mostly a European issue but is alienating European allies worth it? Is it wise in the long term? Will it ensure peace in the world (I don't think so)? And purely from a US point of view, is undermining US influence internationally a good thing for the country's interest? Also, if Trump is so keen on staying out of war, why the inflammatory rhetoric on Canada, Greenland etc. (although we haven't heard that in a while)
Lower taxes - for whom and at what cost to the most vulnerable?
