Becoming a physician is one of the most demanding and costly professions to go into. After 4 years of college, another 4 years of medical school, and then anything up to 7 years of residency training -- this path is not for the fainthearted. Average debt upon finishing school is around $200,000, so it's no surprise that doctors want a good salary when they are done with residency. Most of them first went into medical school with very altruistic intentions. Studies show that more than three-quarters chose medicine with the simple desire to "help people." Most new graduates after residency still have those very altruistic intentions and high ideals, yet after a couple of years in practice -- something seems to change.
