I get your point though. I'm an evil capitalist who doesn't want to fund Americans because they are unwilling to give up 7% equity, or something like that. Maybe you think that Sergey Brin and Paul Graham stole their jobs from some hard working, native born Americans.
That's the problem with zero-sum thinking. You believe that in order for a foreigner to get ahead, an American must be pushed back.
I have the opposite view. I believe that much of America's success is rooted in having an open and inclusive culture that attracts smart, ambitious, and determined people from around the world who come here and pursue their dreams. And that when they succeed, we all benefit. To me, anti-immigrant is anti-American, both economically and ideologically.
