Because
more than five percent of the population gets to make those kinds of decisions every day.
Air traffic controllers face pressures far in excess of doctors, as do harbourmasters, police, fire, and that's in less than thirty seconds of thought. The amount of training required is irrelevant to the amount of pressure.
Try another one. Of course, you yourself probably have no problem affording doctors for your kids. As I said, you probably don't appreciate the position of someone in your society that's not in your shoes.
Here's another question. Do you think CEOs deserve tens of thousands of times the income of their average worker? After all, they have tons of training, face a lot of pressure... MBAs are graduate degrees. Surely they deserve it.
Personally, I don't give a rat's ass about how badly fucked your healthcare system is, since I don't have to live under it. However, the idea that all doctors (or even necessarily all good doctors) deserve to live in the ranks of the extremely wealthy is simply dumb.
