Now back on topic, where do you see the people moving if the economy crashes similar to 99-2003?
Europe = Can't see many people begin to able to move there, people who have lived there before or have family there will probally move there. Young adults who have some cash and EU-pasport try to move there. Most Argentines with foreign partner/husband move there.
USA = People without EU pasport have to go through immigrations and will easily be denied, Argentines with American pasports move to the USA, some Argie families will be able to absorb family members coming over
Latin America: I expect that many professionals will either move to Brasil, Chile, Uruguay, Colombia, Mexico or Perú.
Australia/NZ/Canada: Some maybe on work-visa/study visa, etc, but very low numbers
Rest of the world: Prolly almost 0
Can't see many people who have the ability to move, especially not in the same numbers as in the last crisis.
