Except there is that competition for high compensation workers. I'm proof of it. I was imported from New Zealand to the US to take a job at a wage an American wasn't willing to accept. That it was $160k/yr doesn't change that my employer couldn't find anyone at that wage. In fact, they couldn't find anyone at that wage + >~100k, because that's about how much they spent to hire me, move me (lawyers + immigration), and keep me legal. My entire career has been spent moving from country to country and (essentially) taking jobs at wages locals aren't willing to work for.
