Do you have the same expectation of self-sacrificing patriotism from, say, a non-immigrant millionaire (there's a lot of those around, especially in booming real estate markets), who sits on a mountain of wealth instead of 'helping their host country'? Or is it just constrained to middle-class immigrants, who are trying to help their relatives survive a pandemic?

Christ on crutches, this has an odd air of xenophobia about it.
