Doctor's office bills for X and Y, but insurance will only pay for X and half of Y. Then I have to fight the insurance company to pay for Y.
This back and forth between the doctor, patient, and insurance company is highly unnecessary and the only benefactor is the insurance company. One could argue that the private health insurance industry is actually causing costs to go up because doctors, hospitals, and clinics have to submit detailed medical billing codes to get properly paid for their services.

If a quarter of spending is paid by private, it isn't single payer.
The reality is that when people talk about "single payer" they talk about systems where the essential services are insured by a single entity, not a system without any private healthcare, because none exists.
Also, your insulin shot doesn't cost $1000+ in Canada either. You're a troll, bolstering false information.
