While there may be some countries that disallow private healthcare entirely, the international situation is far more nuanced than your comment implies. For example, I lived in Spain, where most people use the highly functional public health system but there is a parallel private healthcare industry that is also very effective (and still reasonably priced, compared to private healthcare in the US).
