I don't think that's a good way to think about the modern economy. Large companies aren't American, German or Polish just because they're founded in one place. The surplus value that a country like Poland adds or that all the producers in the supply chain of Apple or Tesla add are real and contribute to their national economies.

Singapore isn't a "fake rich" country because most of the companies that have settled down there are international businesses, the money is as real as anywhere else, so are the jobs. Always strikes me as a bit atavistic when people talk about companies as if they're owned by a country despite the fact that the value creation and supply chains run through two hundred countries.
