Medicare-For-All, rather than being "unaffordable", would actually save trillions of dollars over the next decade, according to several studies—and that's while providing *all* Americans with comprehensive healthcare. Here I take a deep dive into the data on this question, especially focusing on the widely-cited Mercatus Center study by Charles Blahous, outlining its many flaws and inaccuracies. I also examine physician support levels for single-payer healthcare, and finally debunk the common misconception that money spent on healthcare via tax dollars would be *on top* of our current spending—rather than a more affordable substitute.
