> If Mexico was the same population of about 100 million and the US had 33 million instead of 330 million people but was just as wealthy, would a single Mexican illegal alien be dissuaded from attempting to sneak across the border? Of course not. Obviously, if the US was ten times smaller there would be 10 times fewer jobs, so yes the flow would be much slower. >> You need a pretty high salary in SF for example if you want to enjoy the lifestyle of a nurse or street sweeper in Copenhagen. > Ah yes, as we can see from the massive flow of Americans moving from San Francisco to Copenhagen to work as nurses and street sweepers. Your logic continues to amaze me. I live in Copenhagen and have some friends with pretty basic jobs. Even a kindergarten teacher can live in a (small) apartment downtown, walk/bike to work and have her kids in the best school in Denmark, and we all have the same healthcare and access to university. Needless to say everyone gets 5-6 weeks holiday a year, works at most 40 hours a week and in general have much more pleasant life than someone earning 150 k in SF would have. But again, how many Americans do you think could even place Copenhagen on the map? Let alone would consider learning Danish. Canadians are much more cosmopolitan, so why do you think it would be comparable?
