This person probably have a substantial administrative position that adds to their compensation. I don't know the MGMA data for FM, but usually non profits need to justify their salaries, eg can not exceed 75%ile for the specialty. $380,000 seems high for that.
It is interesting to hear a family described as having a "median income." You have a large family and half make above $29,999 and half make below? Do you think the education, resumes, skill set, demand for the lower paying jobs deserve much higher pay? How about the hours the lower paid family members make, do the work full time or do they work nights and weekends?
The other thing I will say is that most of the folks posting here who are put off by the supposed complaining about decreased salaries will be complaining themselves.
One thing I learned mid residency (from my own introspection on how I had internally criticized actions as a student/intern) is to not judge your upper level. You don't have the same prospective they have, and you usually realize where they are coming from later on. I'm not saying everyone is right, just take mental notes and think about later when you get more prospective, rather than going around thinking people are unethical, bad clinicians, greedy, etc.
