What's the rationale for this? Like if you're already close to full employment, this isn't even zero-sum, you're throwing away your comparative advantage and spending part of your economy on production rather than higher-value services.
I'm willing to spend part of my country's wealth to counteract, say, other countries' lack of environmental protections, but if you're spending that wealth on counteracting lower offshore labour costs... in effect, the net impact is that you're just reducing the value of your own labour to match the offshore labour. (ergo, tariffs are a real clunky way to support local labour that isn't competitive with offshore labour costs... you could achieve the same ends more efficiently via income taxes and UBI.)
