Medicare for all is about creating a place for big insurance to dump the most costly to insure. Big insurance wants a guaranteed Federal safety net insurance plan to unburden them once and for all of the chronically ill, obese, mentally ill, etc. It's much more profitable to operate in a highly regulated environment, if you're only obligated to cover the healthiest segment of the population. They goal is to continue weaseling out of covering more and more of the outliers.
