Slightly unpopular opinion: All official lore is crap and should be generally ignored. (Even the stuff I kind of like) If I want to play in a world where what I can do is limited by the generic, inoffensive, middle-of-the-road, crowd-pleasing writers at some corporation I’ll just play a AAA video game. The ability to be participatory in the creation and evolution of the in-game world is what makes TTRPGs different from consumer media. Why would you give that part up, but still leave yourself with all the cognitive load?
They said ‘for pleebs’ not business patriarchs. For ‘pleebs’ the answer is:
For each thing you want to buy, ask, ‘is this, and and every part that makes it, from my country or one of the ones we don’t have tariffs with?’ If no, price increase. If yes, no change or maybe a small price increase. (if tariffs push the international product’s cost higher than the domestic’s, the domestic producer may choose to expand their profit margin rather than maintain previous prices)
