For Warren to be fuzzy on details makes a lot of sense. But it looks bad on a stage. People want 10 word answers to 10,000 word problems.
The fact is that any implementation of universal single payer healthcare is a 10 to 15 year transition. It transcends any one POTUS in office.
Suppose the Dems win a majority in the House, Senate and the POTUS - it is still 2 to 3 years before a complete bill with an actionable funded plan can be brought into law. My guess is that NO ONE has invested enough to have a day one plan ready - it is a complex problem. Basically, single payer means removing the bulk of healthcare from a "market" and treating it like a mostly regulated system.
I am 100% in favor of this transition; it is not a quick change. At 63 years of age, I expect to be gone by the time any such system is fully functional and refined. This is a generation change subject, not a 4 year fix.
Here are a few minor details in any such transition:
The Health Insurance industry employs 894,000 people in the United States. There are 273 US companies with a primary industry of "Health Insurance". Yes, a few of them are also "providers", but most are simply in the Insurance and claims processing business.
The Health Insurance industry is just under a Trillion $USD annually. So ignore hospitals, doctors, nurses and pharmacists. Just the health insurance industry employs almost a million people. (BTW, this is one symptom that the system is broken. There are 1.1 million licensed doctors in the US, and - you guessed it, about the same number of doctors working in healthcare as there are employees in health insurance.)
So a change to single payer is a substantive shift, and it needs a proper plan with a transition. Otherwise, if we take the "Medicare for all" proposals literally, we will need to fire 894,000 private sector insurance employees and hire at least a quarter as many Federal employees to manage a system.
See table of health insurance providers below. Of course there are some errors in the table, but by and large, it properly scopes the industry.
