Outside US free healthcare is a thing, in Spain for example if you get ill you can get a free diagnostic and treatment if it is a severe illness (cancer, prosthesis, etc.). Here people is happy with our healthcare, you get healed for free and it is paid with the taxes we all pay.
Of course we also have private healthcare but people prefer public one (because you need to pass a lot of tests to enter there and only the most qualifies people enter and because it is free).
