Pay is only one of tens of factors. Pay is higher, but outgoings are far higher too so it is relative. Pay also is not the only factor in a good life.

Yes but if you come from a poor country, pay outweighs everything else. Without money the kids may get a crappy education (and I mean really crappy where the teachers intentionally don't teach), really crappy healthcare, and no hope of owning property, possibly little hope of owning a car, etc.

Yes compared to developed countries the US may look bad, but most of the world is below the US. Stuff like ICE simply doesn't even register. They've killed only a handful of people.
