As I see it, the feasible alternative is very simple and clear, but it is not what you, anarchists and those sympathizing you, would probably love to hear. Nowadays, it is much easier and less troublesome to emigrate than it was even 50 years ago. The more national economics will be intertwined in the future as it is happening today, the more transparent national borders will become. So my point consists in making states peacefully compete for their human resources by means of providing better conditions of life for their population...
In fact, this process is already unfolding right now
I think you need to talk to the people who lived 50 years ago and ask them just how easy it was to emigrate compared to today. My parents and grandparents told me stories where they would almost pay you to emigrate (from England to Australia). Not the case today. Today the process is much more arduous.
You talk about particulars whereas I talk about the whole picture. We shouldn't take some single cases, we should look, before all, at the average level. The globalization right now moves masses of people around the globe, just take a look at the number of foreigners in Europe...
No passports 100 years ago either.
So this in effect would mean that you couldn't actually go anywhere...
