How other countries finance their health care is incredibly wide-ranging. The point is that revenue-raising tax policies are being included in proposals to close the gap, not that they mirror how Germany and France do it exactly. Some candidates have not put forth detailed tax plans but nobody is saying we won't have to significantly raise revenues to pay for it.

> projected $30 trillion over the next 10 years

This is a projection and there is much disagreement. If we spent as much per capita as Canada, the cost would go down by around 50%. Single payer is not feasible at the cost per person the US currently spends. Every other country in the world spends less (a LOT less). We have a lot of real examples to follow.

> Actually, middle income earners "have the most to lose."

You have a good point, here, but again it could vary significantly depending on revenue-raising changes that are enacted. The Sanders plan includes mostly progressive tax changes.
