I hate to risk the invocation of Godwin's law here, but the primary proponent of autarky (producing everything you need in your own country) in the 20th century was, in fact, the Nazis.

Farmer subsidies drive our businesses offshore. Fannie Farmer just moved their factories to Mexico because they couldn't sell candy competitively using American sugar -- too expensive due to the tariffs.

(producing everything you need in your own country)

Who said everything and when?
7 trillion in debt and 500 billion annual deficit comes actually from importing everything, not producing it. Barring the non-producing service sector and the building industry, pretty much everything else is imported. So it's Nazi to want to leave in an economically solvent and independent country. Well, doesn't matter how you call it, people still want it - the better word for it is patriotic.
