Considering U-6 unemployment is about 12% right now, perhaps this is a feature and not a bug. I still don't understand why Disney and others are allowed to do the things they do with abusing H1B's. Or why firms think they need someone with some fraudulent/substandard foreign degree instead of investing in domestic workers. There's a discussion about labor to be had here and it should be focused on domestic labor abus…
Its a cute fact that you and the hiring manager were both lucky enough to have parents who lived in the U.S. when you were born, but that doesn't make you a better or more worthy person than someone born in a poorer country. (You already have access to a stronger social safety in the form of unemployment, social security, subsidized healthy insurance, etc if you find yourself unable to compete with foreign talent.)
The idea that some people should be considered more worthy than others by our society just because of where they were born or who there parents are is the definition of xenophobia and racism.
You should read up on the literature on brain drain. In addition to your comment being morally abhorrent ("people born in poor countries should be forced to stay there and fix shit so people born in rich countries don't have to deal with it") its also not well supported by the facts. Giving people the chance to get high returns from their education incentivizes a much larger group of people to invest in their education than end up leaving the country.
Given that the same worker ends up making 2-3x in a developed country what they would with their exact same skills in a poorer country and ends up sending much of that extra money back in the form of remittances, immigration is generally a positive force for those "left behind" (not to mention those who immigrate).
