It’s not that simple.
The US health coverage system would be the most complex on planet earth according to the article referenced below .
Indeed the author of the article published in the rubric “perspective” of the new England Journal of Medicine wrote (quote):
“…the ACA was crafted to leave in place as much as possible of the preexisting system of health insurance. The problem was — and is — that this decision meant that reform had to be built on the most complex, kludgy, and costly system on planet Earth. Multiple layers of health coverage — as a fringe benefit of private employment, as compensation for military service, as public charity for the poor, as public coverage for the elderly and disabled, and as a private commodity purchased by individuals in a remarkably dysfunctional market — overlap and intersect to pay for care through a bewildering variety of agents in a system that even experts seldom fully comprehend.” (end of quote).
Until now I thought it was the French system that occupied the top place with numerous special schemes. If you want to have an idea of the French system you can consult the document issued by the French Agency for the Development and Coordination of International Relations (ADECRI) .

Anyway, be it in the US or in France, a nation wide health care coverage system unavoidably has to be complex if it intends to be comprehensive.
