Progressive economists support M4A. That is no surprise and, of course, they claim all the benefits you have heard before, but avoid talking about any consequences that people should be aware of.

Public financing for health is not a matter of raising new money for healthcare, but of reducing total healthcare outlays and distributing payments more equitably and efficiently. Implementing a unified single-payer system would reduce administrative costs and eliminate individuals’ and employers’ insurance premiums and out-of-pocket costs.
