Oh yeah health insurance companies famously siphon off less money than government single payer system. That's why all countries with subtle payer systems spend less money and are healthier overall than countries that use private insurance. Oh wait, what's that? The EXACT opposite is true everywhere in the entire world? Could it be possible that you're wrong about government corruption in Canada? How could that be, you seem like such a rational well adjusted person. So weird, it must be a coincidence, or some kind of socialist conspiracy where socialism makes everyone live longer and spend less money but somehow evil.
