Heard the story of a french woman (who had a heart condition problem) who went on a trip to the US with her family. Just a few days before returning back, she has a serious hear illness problem, must be operated, kept in the hospital for a while then released.
She returns back to France (cured) and starts getting bills one after the other ; the French Social Security reimburses her the part she would have been reimbursed, had the same problem occured in France. It's peanuts compared to those bills.
And of course, the US bills are so high she can't pay them.

Morality: 1)It's about time there were treaties between the EU and the US concerning medical aid.
2) Don't get sick in the US; it's billions of lightyears away from the country of hope and opportunities, in that case. Especially for foreigners.
