pay is irrelevant. When you make $20000 a year its easy to say $150k is easy living. thats a warped way to view the world. and a jealous one.
You have to look at what it TAKES TO EARN that kind of money. Doctors dont just go to the local community college and major in art history and get 200-500k jobs. I know doctors, i work with doctors, my GF runs a major hospital admin . It takes unbelievable education and $$$$ to become a doctor which is why they get compensated well.
