What makes the US border so much more meaningful than a state border? Why do you care about somebody living potentially 3000 miles away from you on the other coast more than somebody who lives much closer in Canada or Mexico? Why is immigration from places like Kansas to the valley seen as a positive sign but immigration from India to the valley is seen as stealing jobs?
I care more about the Americans because they're Americans and we're on the same team and that's what teammates do. Also, how they feel affects how they vote and how they vote affects me. We have to look out for each other because the Canadians, Mexicans, and Indians sure aren't going to look our for our best interests ahead of their own. Why would they?
I don't understand why this is such a strange concept to so many people.
Immigration must be (1) strategically planned, (2) closely watched, (3) carefully governed. It is a lot of money, who (and why) is going to pay for it? There are no other problems left to solve?
