It is not fair to compare taxes between countries with and without healthcare, but it is almost impossible to compare otherwise. For example USA has huge prices and excellent services compared to almost any other country, in my country (Romania, Europe) the socialized healthcare is so bad many people have a private insurance, I have 2 private insurances through my employer and I still pay out of the pocket about half of everything I get (100% of dental care is out of the pocket, most consultations are covered by the private plan, most treatments are out of the pocket).
