We had a revolution and a civil war and unrest to fix our own failures. They can work to improve their own self determination. Look, Panama 25 years ago was a basket case. But now they are one of the better economies of the southern cone.
Tell me more of this “our own”. 25% of the current US population is either 1st or 2nd gen immigrants arrived after immigration reform of 1965. They include the innovators, laborers, entrepreneurs, researchers that pay a lot for your “our own”. Can’t eat the cake and have it too.
That's not entirely true everywhere though. For example, I was born in the US, as were my parents and grandparents. My great-grandparents immigrated from Italy, and if I can gather the proper documentation, I'm eligible for Italian citizenship. If I ever get this done, then yes, I could indeed go back to my great-grandparents' country and do what you suggest is silly. I believe quite a few other countries also have policies like this.
It actually kind of seems like we can do this. We do that by increasing the visa requirements, as this new directive is doing so.
It's infinitely better than importing huge numbers of uneducated fundamentalists whose culture is incompatible with the western values and includes throwing gays off of roofs.
It's better to have a few shining examples of truly great countries in the world, rather than mediocre mush everywhere. So citizens of other countries can point to such countries and tell their politicians and their friends - see, we can do better, much better.
That and US doesn’t need to pay a dime for them developing their skills while getting to skim the cream of the crop.
