As a matter of fact, I can't recall ever reading an op/ed or anything by a hospital administrator complaining that they're being fleeced by medicare and losing a bunch of money on it. But I've seen a billion op/eds in the same template as TFA, bemoaning the byzantine and obfuscatory private insurance regime as something that completely destroys any market forces that should exist in the industry. I mean, one hospital charged one thousand times as much as another for the same treatment.
I have to conclude that bringing up medicare while the private insurance industry system is this flagrantly broken is nothing but a red herring.
