| Wealth to who? An immigrant will capture a much smaller share of the value they generate, otherwise why use them, than a native born citizen. This means that while theoretically 'wealth' is increasing it is increasing in such a way that those who are in the position to pay wages keep more of them and those in the position to receive them get much less. In short then what's the point of an average in a power law distribution which by definition does not have a defined average? Or to put it even more dumbly would you rather live in a world of 100 units of wealth distributed between the 5 quintiles as [80.0, 16.0, 3.2, 0.64, 0.128] or one of 20 units distributed as [6,5,4,3,2]. For 2/3rds of the people in the world the second would be better. |
Why not use them, if they're more qualified?
The only reason why employers can fleece immigrants in US today, is because immigrants are effectively "locked in" - e.g. if you're on H1-B, you can't change employers without going through a bunch of paperwork; and if you get fired, they just kick you out of the country. Which, obviously, means that you can't negotiate from the same position of strength as a native. But remove those, and why do you think an immigrant would demand to be paid any less? We're not stupid.
