All countries mentioned also control their populations. They do not have the immigration that the U.S. has. When they tried to do so, as the EU did with Africa, it overwhelmed their system and they stopped. You cannot just enter these countries without having gainful employment and paying into the system. It is a social net for the payers. Non payers not accepted or welcome. Also, you don't see these countries reaching out to the rest of the world to help. They help within themselves, but not to others. What Norwegian naval vessel (if they even have any) shows up when another country has a disaster.? My wife had both knees replaced. was done in months after tests and such. Our friend in Canada had to wait over 2 years to have one knee replaced. And Canada is what size compared to U.S. We have issues for sure, but still favor our system over anyone else's.
