LOL. As a matter of fact its only the doctors who are in govt. service who make decent money. (Not legally)
Contrary to what your believe, doctors do not become doctors out of the goodness in their heart and a desire to server the poor
Last point is that in pvt. hospitals, each doctors have a "quota" to be filled. The amount of revenue they need to generate if they want to stay on in their jobs
.........this 'quota' of money to be made for the hospital extends to all kinds of 'experts'...from Neurosurgeons to radiologists.
The next time you go to a doctor, remember that.
