There are singular companies doing extremely specialized work for entities all over the country, so this kind of logic is not going to work. It would be more realistic (but similarly problematic) to apply the logic on a national level. But what that would look like is the government issuing licenses to import based on the percentage of the company's output made domestically. That is complex to figure out, as well, and not all products are made entirely in one country. Even if they can be made all in one country, it may not be what you want your countrymen working on. I would rather see my people make cars than, say, squeaky dog toys. But some of the same skills can be used for a variety of different products too.
