The net result of the former is lower drug prices for the US public and a more complex supply chain that will be (ab)used by our already overly complex healthcare supply chains in the US. More indecipherable drug prices and negative externalities from exporting and then re-importing drugs like higher carbon footprints don't seem desirable, even if they're more palatable to the direct policy-averse conservative public.
The net result of tariffs is some combination of: higher costs on the goods purchased by Americans, lower wages paid to the workers making those good, and reduced demand on foreign goods (which may not have a substitute, which may depress the economy). The latter, reduced demand on foreign goods, may in turn hurt foreign economies, reducing their demand on our exports.
Somewhere in that is "higher wages for industrial workers", but it's unlikely tariffs lead to that outcome except in a handful of cases where the US has production capacity available for a substitute good. US steel might be one of said exceptions, because we have large amounts of unused capacity and a comparable or better product, but aren't able to manufacture it as cheaply. It's highly unlikely tariffs on ... checks notes from [1] Alaska pollack (interesting!), child safety seats, and hydrometers are comparable. I don't expect we have huge amounts of latent labor supply just waiting to make these things or manufacturing facilities configured to do so, but I could be wrong.
The net effect of a massive tax cut that disproportionately impacts the wealthy and tariffs that disproportionately affect (nay, target) consumption goods is a regressive tax hike on the majority of Americans.
These aren't left-wing outcomes, they're just bad policies.
