In rural America, we have been importing doctors from other parts of the world because we don't have enough American doctors who want to serve outside the big cities and high-paid specialties.

That's probably because foreign doctors don't know what they're getting into. From speaking with American doctors, many have been offered double the salary to go to rural and non-rural positions in the south and Midwest but they would not even consider it due to the racism and hate there. Can't say I blame them. I'd do the same and I'm white. Culture matters and having a culture of hate like most of rural and quite a bit of non-rural America does is extremely unappealing especially to people smart enough to become doctors.

Perhaps, but outside of the FAANG bubble, income levels have been stagnating for quite some time (if you adjust for inflation)

Salary is not enough to determine quality of life, a faang salary in the Bay Area doesn’t get you very far as an individual and for families it’s often not enough.
