About people in "shithole countries"

Some countries will never prosper, lacking too much in usable resources or opportunities.

So people try to leave them for better places.

And so there are economic migrants.

Just the sort Trump wants to keep out, the sort who comprised most of our immigrants to the US throughout our history.

Including my ancestors on both sides, my father's parents and aunts and uncles and my mother's parents' parents, all down from Canada looking for work and a better life.

As for Syrian refugees, see on Amazon We Walk Together, about Syrians walking from Budapest to Western Europe.
