People who like to take risks very rarely enjoy the kind of straight-jacket social environment you find in Western European societies. Therefore, they leave for greener pastures.
Government mandated social security is an extremely inefficient way of managing health care. As an added evil it puts a giant drag on how fast companies can move.
But in Europe, try to dare to even mention the idea that centralized government mandated social security is terrible and you're immediately ignored because people think you're an immoral person. And social metrics be damned.
Just another example of Europeans living withing the confines of carefully built and maintained mental prisons.
