The regime is offering contradictory explanations though. For one they're citing the rationale you've explained here, that's its about reshoring manufacturing. Let's set aside all the reasons why that almost certainly won't happen for a minute, some spokesmen for regime are also justifying them as a negotiating tactic to get better trade deals. And yet others are saying that they're a way to raise revenue to pay for tax cuts elsewhere.
You can see how these are contradictory right? If they're for reshoring manufacturing, then they need to be stable and predictable so companies can plan ahead. But if they're a negotiating tactic then you can't take the current rates for granted so companies won't invest on the basis of the current tariff rates because they're expecting them to be adjusted through bilateral trade deals. And if you want to impose them to raise revenue to pay for tax cuts then you wouldn't necessarily want manufacturing to return because that would eat into the revenue from the tariffs.
You can't incentivize manufacturing, negotiate a bunch of bilateral trade deals, and raise revenue from tariffs all at once. The more likely explanations is that Trump generally has no idea what he's doing and has almost a voodoo like belief in the efficacy of tariffs and so he's decided to slap them on against the better judgement of anyone who knows better and now his cronies are scrambling to justify it by reaching for multiple, contradictory explanations. Do you think I'm getting anything wrong there?
If this was really good for US manufacturing why wouldn't stocks associated with US manufacturers have gone up? Could it be because US manufacturers have supply chains across North America and the world so that even they will suffer from these tariffs?
Kamala was talking about economic issues though, much more so than cultural ones from what I remember. For example she was advocating for bringing back the expanded child tax credit which is a policy I strongly support and was one of the big reasons I was voting for Kamala aside from wanting to see Trump lose.
I didn't even agree with all her economic policies like the $25k subsidy for first time homebuyers(bad idea in a high demand, low supply environment) or the tax on unrealized capital gains(discourages investment and hard to assess) but I don't think its fair to say Kamala was only talking about cultural issues when if anything it was the Trump campaign that leaned heavily into said cultural issues.
The one economic policy Trump ran on, 10%-20% tariffs across the board, was so stupid that even supporters had to caveat their support for him by saying he would obviously not do it even though it was his signature economic policy.
