“If we had a single-payer system, the overhead costs would be less than 5 percent, and 95 percent would go to actual medical care.”
No you would have even more manipulation of prices and disbursements in order to meet those percentages but sooner or later real costs would catch up with these false expenditures and the system would start collapsing. At least that is how I see it.
I work with a lot of people from Canada, the UK, and NZ.
They all complain that we don’t have single payer, till something major happens.
One gentleman told me he liked it (single payer in Canada), but the quality of care was less.
