Is she really underpaid? The average pediatric critical care physician in the US makes $262K-$440K a year according to Glassdoor.

This is twice what the same role pays in most European countries. Unless she is well below that range for some reason, she is likely overpaid.

Everybody in healthcare, from the nurses to the hospital CEOs, makes far far more in the US than they would in a country with socialized medicine.

That was really not meant to be the focus of my comment, but that range definitely seems high, from all those that I know in the field. You have to also factor in the significant amount of debt they incur over the 14 years it takes to get through undergrad, medical school, residency training and then subspecialty fellowship training. Adult ICU doctors make twice as much as pediatric ICU doctors, that was really the thought behind the comment on being underpaid. That, and she works difficult hours (long shifts, nights, weekends, holidays, on-call, etc.) and the emotional toll of the work can't be understated.
