Oh I have compassion for them, I never once said immigrants are bad people, never would, but hey I'm not Donald Trump.

But I think we should look at how badly resources are stretched here before letting the whole world in, which doesn't mean have zero immigration at all. But I care about quality of life in the U.S., which I know must be a sin or a thought crime or something to care about until all of Indian is lifted out of poverty or something, but how can one not, one has to live here. And some will say "how can resources be stretched, when the U.S. uses so many resources?". The U.S. uses too many natural resources in general and it's not sustainable. But I don't mean whether we have enough iphones when we insist on getting a new one every year, or even whether we waste too much food, but rather things like infrastructure, housing etc., some basic things in life that could all be very broadly classified as infrastructure, all stuff larger than individual consumer decisions, seems stretched to the breaking point.

As for whether people came here from Europe or not and what that says about contemporary Europe or the U.S., IMO not much. Europe was devastated by WWII. Even before then I can trace some ancestors who came here to escape the rigid class system in England. All very well and good, but the U.S. has one of the lowest economic mobilities in developed countries at present. That was then, this is now.
