There's a ton of inefficiency in the system: administrative, lack of preventative care, lack of continuity of care, that hospitals are forced to provide critical emergency care to anyone who walks in and can't afford it, cost of drugs, and yes, the amount doctors are paid, and the amount doctors have to pay for malpractice insurance (which is also socialized in Canada dramatically reducing cost).

Doctors become public servants. They should get paid relatively comparably to other first-world countries but the fact is what they're getting paid right now is unsustainable for us as a society if our goal is to cover everyone at a reasonable price -- and it should be. Preserving doctors top-0.5% pay is strictly a non-goal. Building a functioning public health system is a goal.
