> In no country ever is private healthcare and competition banned. There is a free* hospital across the street from me and I have private healthcare.
Thats not factually true: there are many places that ban private healthcare, including canada.
Then there are other conditions that punish private disproportionately: like funding public healthcare with taxes, but private healthcare with private funds: that means a person would have to pay 2 insurances to get private services.
Also single payer really means there is only 1 insurance, so yes, it bans all other insurances.
> It’s about acknowledging that a) it is cheaper for everyone if people with no money go to the doctor early, because a GP is 1k% less expensive to society than a hospital bed runout. This is one of the reasons healthcare in single payer countries is ~50% per capita.
There are multiple issues why healthcare in the US is more expensive than "single payer systems", and preventative medicine is a small part.
> people without money don’t deserve to die because they are poor and should have basic treatments, even when it is their own fault they are poor and make bad decisions.
Is this moral line of yours defined by the country? Because if you want to save people's lives, single payer systems are very expensive. Its a lot better to open immigration and bring poor people from abroad.
