Comment Re: Don't tariffs cause all price inreases? (Score 1) 91
The last century is littered with examples of nations with "truly self sufficient" economic policies and explicitly anti/deglobalization - they used to call it anti-imperialism but it was the same goals, same tools. Many were successful on those goals - drastically reducing imports, moving industry production into the country, etc. None succeed in keeping a competitive economy or sustaining (much less improving) quality of life.
To be fair, the old social-democrat experiments did not try the "lets change the tariff every week" approach. Usually they defined a plan and policies stable enough for that local manufacturer to plan, build or upgrade the white-chocolate industry to supply the local demand. The scarcity and empty shelves came at the end of the five-year plan failure, not at the beginning.
