What stops any group of people from being sloppy or corrupted? I called out the things that keep single-payer systems in check in my original comment, which you’ve replied to: pressure from constituents keeps premiums low (in the same way that the government is pressured to keep taxes low by their electorate), and they’re incentivized to negotiate low rates with providers because it improves their ability to keep premiums low without having them be lower than expenses. That said: the US’s current privatized system is sloppy and corrupt in a multitude of ways, because their incentive structure includes turning a profit, and they can’t negotiate costs as hard as a single-payer system can, because their pool of customers is smaller. So we’ve got the worst combination of traits.
