Everyone would like to be paid more. Complaining about how much you make is as much of a great American pastime as baseball. Perhaps more, since you don't need a ticket to the ballpark in order to join in on the fun.
Some folks, though, are legitimately underpaid. U.S. News and World Report looked at 7 jobs with high (or at least medium) satisfaction ratings but low pay. "Low pay," in this case, was below the median salary of $41,673.83, as determined by the Social Security Administration. Significantly, all of these jobs are in high demand, which makes their low pay even more puzzling.
