Does a preference for "meaningful" work necessitate a lifetime of modest compensation? Not for those who choose to go into medicine. That's the finding of a new study from the online salary- and benefits-tracking company PayScale. Using data collected from about 374,000 PayScale site visitors, researchers at PayScale found that doctors tended to have the best combination of high compensation and a positive response to the question "Does your job make the world a better place?" Overall, the group with the best combination of meaning and money is surgeons, 94% of whom report finding their work meaningful and whose median compensation was just shy of $300,000. They did, however, also report high levels of stress.
