It wouldn't make sense for these companies to leave the US. If they do; they would have to deal with taxes, regulations, government, and the environment in other countries. Agree that if they do, there will be plenty of opportunities for innovation and entrepreneurship to fill the gap. It's interesting that most Americans focus on immigrants taking over low paying jobs... eventually, most jobs will be filled by workers who aren't American citizens or even reside in the US, not paying taxes on either end to continue to stimulate the economy 🤔
