If we add people into the system that aren't currently paying in because they can't afford it, and we add insuring pre-existing conditions, then it'll still cost less because the profit incentive will be removed and we'll have soaked the rich.

Which is why, of course, countries who have universal single payer have scaled back what they're willing to cover to the bare bones and they're still in the red.
These idiots will believe anything.
