Universal health care = lack of overall quality of health care. Period

Without constraint, healthcare can happily consume a nation's entire GDP. So in the end, once you get past issues of vocation/profession and (mostly religious) charity, healthcare quality is determined by rationing. Some systems ration by being unaffordable for many/most; others with waiting lists; most by declaring that some expensive treatments may be only part-funded or not at all. Your own policy may have some or all of these elements. FWIW, quite a few of the universal care countries also have private systems so you can elect to go private if you want a different level of care. In one such system outside the US a family of five would be looking at perhaps $700/year insurance to cover private surgery expenses if they decide to go private.
