The mechanical knitting machine was invented in 1589.

The Worshipful Company of Framework Knitters was incorporated in 1657 London.

Some framework knitters were among the Luddites, who resisted the transition to factories.

Even aside from the argument about production never actually leaving developed countries (only the non-automatable stuff left, the rest is growing faster than ever) this won't really have much benefit. If people in your country are buying the shirts these companies make there is already tax being taken for them and it's not like they'll add enough jobs to even notice, that's the whole point.

"Perhaps that will be the way the most developed Countries will return some of the production lines to them"

Why do you care about that? ecology?

It's not like if it's going to translate in jobs.

Less transportation required, which should be cheaper and better for the environment.

Someone would have to build and manage factories. Would need a night guard to feed the guard dogs too :)
