As far as I understand residence, being a RN means working like a dog for essentially no pay - in any country, be it Sweeden, Canada, the United States, or China.

Pointing at a RN to make an economic point is like pointing at the Wall Street interns pulling 130 hour weeks for lunch money as an example of how the poor financial industry is overworked, and underpaid.

In Denmark its not strictly necessary but many do so they can afford an apartment instead living in a dorm and/or more expensive lifestyle. Its cheap money though. After education its only the the states lending rate + 1%.
