So where will the extra $16 trillion come from to pay for Sanders' plan?

88. Michael Hiltzik of the LA Times holds forth on this very question:

CHARLES BLAHOUS of the Mercatus Center, a libertarian think tank, is shown in 2014. He wrote a paper that found a slight decline in projected total public and private health expenditures under Medicare for All. (Susan Walsh Associated Press)

The Mercatus Center at George Mason University, a libertarian think tank partially funded by the Koch brothers, appears to be mighty embarrassed about its finding in a recent paper that the Medicare for All proposal from Sen. Bernie Sanders (I-Vt.) might actually reduce Americans’ overall spending on healthcare.
We know this because Mercatus has sent out several emails pushing back against reports about the finding. And the paper’s author, Mercatus fellow Charles Blahous, took to the opinion page of the Wall Street Journal to complain that “some have seized on a scenario in my estimates showing a slight decline in projected total public and private health expenditures under Medicare for All.”
Among those who “seized” on the scenario is Sanders himself, who crowed about it on Twitter after the paper was published at the end of July, mischievously getting the Koch brothers into his tweet because, why not?
Blahous grouses that Sanders and his followers overlook his main point, which is that the Sanders plan would sharply increase government spending on healthcare. He’s got the support of several conservative commentators and not a few credulous journalists.
The problem with Blahous’ complaint, as it happens, is that he actually did find that the Sanders plan could reduce overall healthcare costs. That conclusion is right there on page 18 of his 24-page paper. Under the assumptions in the Sanders plan, he writes, “aggregate health expenditures remain virtually unchanged: national personal healthcare costs decrease by less than 2%, while total health expenditures decrease by only 4%, even after assuming substantial administrative cost savings.”
According to his own math, under Medicare for All, national health expenditures would total $57.6 trillion through 2031. They’re currently projected to be $59.7 trillion. In other words, Medicare for All would reduce total U.S. spending on healthcare by 3.44% (a bit less than the 4% Blahous cited).
Mercatus in its emails cite several ostensibly objective journalism sources calling out Sanders for, in effect, “cherry-picking” Blahous’ results to make Medicare for All seem thriftier than it is. They include Washington Post fact-checker Glenn Kessler , the Associated Press , and Jake Tapper of CNN. Some of Sanders’ critics panned him for failing to give the context to Blahous’ finding; but it’s a little churlish to complain about someone leaving out details from a 185-character tweet, since Sanders has published all the details and assumptions underlying his proposal, and Blahous found them easily enough to use them.
Moreover, those sources engaged in a fair amount of cherry-picking of their own. And Blahous is dancing as fast as he can to minimize the implications of his own math.
Let’s get to the bottom of the controversy.
