Talking about tariffs, I don't have a confirmed opinion about them because I think that, just like many managerial and political decisions, implementing them has so many consequences that the discussion could go on forever.
Also, neither I am an expert in macroeconomics, nor I am a complete layperson, but I'm closer to the layperson.
That said, one thing doesn't convince me about tariffs: as far as I know, there is strong consensus about the fact that each country should specialize in supplying things in which they have the so called
comparative advantage, since in this way, overall, the conditions of each pair of exchanging countries would improve. This is just a general rule and I doubt that it holds true always in every situation, but tariffs should hinder that kind of business.
The problem is also that there are so many causes and effects for political and economical events, that even if we could foresee the future or analyze different scenarios in parallel universes, it wouldn't be straightforward to associate causes and effects and judge decisions.
@Philip: this topic has been involved many times in this forum and after all it is, indeed, related to the success probability of EVs manufacturers. Would it be acceptable to create a thread about tariffs, of course provided people discuss respectfully without contempt for other countries? If so, in which subsection?
