Canada has single payer and rising administrative overhead is a major problem here too. Looking at spending on medical staff vs spending on administrative staff, the former has barely gone up at all while the later has gone up over 500%. Plus we deal with the serious problems of lack of care. I know several people who have waited over 2 years for important surgeries like hip replacements. My mother died because they didn't want to keep her alive, and we get no say in the matter. Single payer doesn't magically make health care work well.
