I think each country should have a first responsibility to its own citizens - getting all of them to some standard of living before allowing immigration or offshoring or importing. This would work for all except a few countries (and then importing/offshoring/exporting by other countries would be able to help them.)

We could simply define jobs for people, and stop importing products in those categories. Need more jobs? Restrict more product importation and offshoring.

I should add that I've worked in factory automation - fully lights-out factories - and we are capable of creating a great quality of life for people. This isn't the early 1900's, we can create all the jobs we want for the people who want jobs.

And there are competing studies about the effect of the safety net - since countries with the best safety nets also usually have the best economies and the most innovation (some think it is tied to the ability to take risks without becoming impoverished if you fail.)
