@jojo: when you’re talking about wait times, the system is broken. Waiting for people to die is not healthcare, especially if you’re asking money (taxes) for the privilege. If government healthcare was better, there would be no wait times, costs would be lower, no such system exists however, medical tourism only happens in a few places in the world and those are universally private systems.
Why would anyone not want it available for free- or low cost, to everyone
Because that’s a myth. Hospitals are expensive places to run, someone has to pay for it. If the government pays for it, that really means that you are paying for it through several middle men so it becomes much more expensive, the only way to cut cost is then to ration health care which is what UK, Canada, Australia and EU does, if you’re 80 you’re cut off, if you’re too unhealthy you’re cut off and if the treatment is too expensive, then we propose alternatives (eg forced euthanasia, amputation, marijuana and other non-medicinal drugs, concentration camps for COVID etc).
The question is why would you entrust your healthcare to a corrupt government system. If you’re talking about private/public systems, you’re paying twice, once for the public system and then again for the private system and because not everyone is in the private system, it ends up being much more expensive which is why people unilaterally go to the US for care.
