What responsibility does a non-citizen shirk? They must follow lows, pay taxes, etc. Even for things like social security.
I sometimes wonder where these concepts come from, because it sounds like somebody tricked you into thinking that non-citizens are somehow taking things from everybody else, rather than contributing just the same as everyone.
National defense, and (more vaguely) a responsibility to keep the host country in good shape as there's no other country they can run back to if things go bad in the host country.
Not even American. Just visited once for a few weeks. The answer is generic, in recent times you can compare how Ukraine or Russia can conscript their own citizens but probably not foreign workers who just work there.
Ok so you probably wouldn’t know that foreign born service members make up 5% of our military, most of those becoming naturalized citizens while serving. They’re not shirking their responsibilities anymore than natural born Americans who don’t volunteer.
