Why should people working in health care be different?

Again, this is not a "should" question. It might be eminently justifiable to tell millions of health care workers that they should earn less money so that consumers pay less for health care.

But you still face the "is" question - regardless of whether those workers "should" earn less money, the fact "is" that they don't want to have their compensation cut. And there are millions and millions of them. Nearly 12% of the workforce is in the health care sector. Which raises a nearly insurmountable obstacle to switching to any kind of single-payer health care system that squeezes medical provider compensation rates. Which they all do.

That's what blocks us from moving to single-payer. That obstacle isn't caused by JC's or corrupt political ne'er do wells. It's caused by the fact that now that the health care sector has grown to its current size, there's an awful lot of stakeholders in the health care sector - and the political process will be very sensitive to those stakeholders.
