I have a very unique experience. Without diving into details, French health care system welcomed and supported and provided very long, sophisticated and expensive care. I really mean a lot. All for unremarkable insurance (mutuelle) 100€ per month.

Mandatory social insurance, basically my taxes, paid for bulk of it.

High level of professionalism, high standard of care, very little red tape and no unreasonable waiting.

Out of pocket it is usually close to zero.
