If you think our current system doesn't have rationing, I'm not sure what to tell you. "Long wait times" are one way to ration care -- but equally effective is just denying 30 million people the ability to get any care at all due to unaffordable insurance and ruinous costs for any 'touch' with the system. Another effective way to ration care is to make routine things so expensive that people self-select out of receiving care or filling prescriptions even when they are insured.
