There is currently no consistent incentives for global multinationals to invest locally when there's "always labor somewhere else." If you compelled local hiring, then the multinationals might stop giving locals the middle finger and invest in a country instead of strip-mining it into an impoverished favela. I don't want to get into divide-and-conquered, tribalism political malarkey, but the people have to push out the corporate corruption and get politicians working for We The People, not just We The Corporations. Without fixing the political system by rising up, the corporations will keep killing the middle class.
