Tariffs don’t “work” or “not work” it’s not a binary outcome. Just as measuring “the economy” is pretty much impossible, so is attributing economic outcomes to one single feature of the regulatory environment, They interact with the rest of the economic environment and some variety or work, production, trade, investment and distribution will occur. Over time all aspects of the system will change, adapt and react. Most changes have winners and losers and they can be counted or balanced off differently.

It it were paired with bank regulation and asset ownership regulation and a coherent industrial strategy, maybe also forex controls, maybe some counter cyclical macroeconomic policy (extremely unpopular these days) the outcomes would likely be quite different from a low regulation free for “all”. “All” is probably “a few with relatively unconstrained access to enough capital or credit to hoover up assets of the losers”.

But then a smaller subset of those things might also change the outcomes on their own. Either way it would be a matter of time and adaptation of a complex system.

It also depends what you think the objective is before you understand “success” or “failure”, the goals might well be social as much as economic. If the objective is trash the small scale asset ownig middle classes and enrich the elites economically then it might be working already.
