Whom should you select to let into your country? The same people you select as employees, only more so.
We use "skilled migration" as a proxy for what we really want, which is people with good genes. If you have skills and good genes then you'll enrich the country not only in this generation but in all future generations to come.
So an ideal immigration policy would involve some combination of testing for intelligence, physical fitness and (dare I say it) good looks.
There are plenty of untalented natives in any country. I do not think the government is particularly good at spotting talent. We should just let everyone in IMO.
Besides, "talent" can mean many things. Is the Mexican mother who can't speak English and doesn't have a college degree (maybe not even high school), but can make BAD ASS food and is capable of raising a family of 5 talented?
