Quite possibly, but I thought Biden's idea was to leave no one without some form of medical insurance, be it Medicare or their existing insurance, rather than to leave people without cover.
I get really frustrated with people who say that Medicare for All is a desirable goal, since that does absolutely nothing about the way healthcare is delivered in the US, which is the real problem -- the US spends far more on healthcare as a proportion of GDP t
han do other OECD countries (almost twice as much as does the UK) with far worse outcomes.
That's not because there's anything wrong with US doctors, nurses and other healthcare staff, but because the system that delivers it designed not to provide quality healthcare to all patients who need it but to deliver a good return on investment to shareholders.
Simply having the government take over pumping money into a broken system seems to me a really bad solution (but then I'm a socialist of sorts).
