It’s truly horrible. How many doctors that you talk to “get it?” I have a SIL (early retirement pediatrician) who thinks single-payer is the way to go, despite encountering the same problems you described in her practice.
Pediatricians are a group that is most used to .gov control. Most of their patients are Medicaid since most States have expanded it to cover most kids. Their group is also run by very,very liberal people. Why has she retired early??
