It has worked out well for our veterans   .
For those readers unfamiliar with US healthcare, the US in effect has several independent healthcare systems. Around 90% of veterans get healthcare through the Veterans Health Administration. It provides a healthcare system that uses the same model the Britain uses.
For Americans 65 and older, we have Medicare, which uses the same model Canada uses.
For Americans who get health insurance through their employer, we are similar to Germany.
For Americans that do not fit into the above three groups, we are Cambodia or rural India, where you can see a doctor if you can pay the bill yourself out of pocket, or if you are so sick that you can be treated in the emergency room at a hospital.
