Have you ever noticed how one egregiously incorrect assertion can poison an entire article for you? In the case of this article by Paul Demko at Politico about “Medicare for All” it was this statement:
Some Democrats use “Medicare-for-all” as shorthand for a single-payer health care system, like the British National Health Service.
The problem is that British National Health isn’t just a single-payer system. It’s full-on socialized medicine in which the government is not only the primary disburser of payments for health care services it actually runs the system the way the Veteran’s Administration runs the system of VA hospitals.
The rest of the article is completely speculative. I won’t even comment on it.
I’m skeptical about M4A because I don’t think the conditions that would make such a system work prevail here. We are too large; we are too diverse; we don’t have enough social cohesion; we don’t have enough respect for authority. We aren’t willing to control costs so they would rise out of control, destroying everything else funded by the government in their path. That’s speculative, too, but at least it’s based on experience, cf. SGR.
