Bright people have a whole world to move to, not just South Korea. For example, I went from the UK to Germany, and my sister-in-law went from the Philippines to the UK.

What about "not bright" people?

Personally? I’m in favour of anyone being free to move anywhere anywhen. I don’t see opposite sides of international borders as being more substantially different than different regions within any single country, likewise corresponding movement of people.

That's my point, I too went from a 3rd-world country to a developed one, haven't seen many people doing the opposite.

I know at least five people who are either doing that now or have done that for a while in the past.

Rich countries pay a lot, poor countries are growth opportunities — in both the personal and business senses of the phrase.
