So, if we're going to follow Switzerland's lead, we would roll back tariffs.
Switzerland is more akin to the EU's version of Massachusetts or New York, and Zurich is the EU's version of Manhattan or SF. It's the sort of economic zone that will always exist in a large economy like the US or the EU. The population is disproportionately made up of citizens from one or two cities/metro areas, and those cities have a high concentration of highly educated and highly paid individuals typically focused on one of a few industries. Consequently, even those employed outside of these high-paying industries make more than average compared to the rest of the country/bloc.
Situating ourselves similarly to Switzerland requires placing the US very high in the global value chain while maintaining a global order of very low trade barriers. Which has always been the neoliberal agenda, at least ostisibly.
In other words, if we want to emulate Switzerland, we have to do exactly the opposite of the Trump plan -- continue offshoring anything lower in the value chain, continue insisting on low trade barriers, continue dominating everything higher in the value chain. Obviously, even if this strategy works for the country in aggregate, it's going ot have definite losers in a country as large as the US.
On a (very!) related note, the US and Switzerland currently have basically the same PPP.
