Got to disagree. If you think federal policy wonks aren't considering salary, you are naïve.
A close relative worked for HCFA (predecessor to CMS) many years ago. A very smart guy who was not terribly sympathetic to doctors (his dad was one). He told me once of having a group of vascular surgeons come up to complain about a new payment schedule and "how they were getting killed". Of course, they flew up in a chartered Jet, dressed impeccably (vascular surgeons) and with nice watches. Needless to say, there was little sympathy and this was not effective advocacy.
Moderately paid federal employees who are part of a large bureaucracy may be more sympathetic to a large system with more modestly paid employees.
If CMS is thinking "these PP docs are pulling down 700+K due to opaque payment schedules". Absolutely that is going to impact targeting of cost control initiatives. If these same docs are claiming crazy things like "they'll have to shut down their practice" when a 30% decrease in revenue is forecast, this is not going to be lost on anyone.
When I see this I think, "pretty fair, less than I make but they hopefully get time to do some research and they probably have more help".
