“Medicare-for-all’s” advocates promise a health care system that’s free at the point of service – no co-pays, no deductibles, no coinsurance.

They tend to be less upfront about how they’d pay for it. Independent estimates from both the right and the left peg “Medicare-for-all’s” cost at about $32 trillion over 10 years. Doubling what the federal government takes in individual and corporate income tax revenue wouldn’t be enough to cover that tab.

That’s assuming “Medicare-for-all” is able to implement its financing strategy. The bill proposes reimbursing doctors and hospitals at Medicare’s current rates, which are 40 percent below what private insurance pays.
