Those are two real effects, but together they wouldn't compensate for the rate cuts.
About 8% of the population is uninsured. The uninsured population skews younger, with less healthcare utilization (Medicare already covers everyone 65 and older).
Another comment in this thread estimated billing overhead at 8.5%. Medicare for All would eliminate some, but not all of this, since Medicare is still a claims-based system. You would remove a lot of overhead around prior auths, which I agree is a good thing, but could be achieved with more focused legislation.
> .. 8% of the population is uninsured. .. this is Bogus, one of the first argument hospitals make for inflated pricing is that they have to cover the cost of uninsured. if the uninsured doesnt exist then the whole line of BS argument falls.
