You're the richest country in the world (Andorra isn't real, don't @ me). And if you want universal healthcare, come and experience the joy of the NHS. I have to actually live with it.
IMO universal healthcare is awesome as the final safety-net that provides critical care, no matter your financial or employment situation. Yet it doesn't need be the only option. If businesses or people with money want to pay more to get care faster from private sector, that's okay too. It's how the system works here in Finland.
* private is good for better rooms, more scenic views, personalised spa like service and near immediate access to non life essential procedures
* public keeps the majority of people alive and triages procedures, you can get overnight heart stent surgery for free if required, might have to wait a few months for non critical knee surgery.
Safety nets would be great, but a net that arrives several days after you have already fallen to the ground is not very helpful. That is what rationing-by-queueing does. Maybe Finland is great - I believe you! Britain's system is not.
