Demagogue

According to a new study, if your paycheck isn't as large as your co-worker's it may be due to the fact that you're short and/or ugly.

A London Guildhall University survey of 11,000 33-year-olds found that unattractive men earned 15 percent less than those deemed attractive, while plain women earned 11 percent less than their prettier counterparts.

In their report "Beauty, Productivity and Discrimination: Lawyers', Looks and Lucre," Hamermesh and Biddle found that the probability of a male attorney attaining early partnership directly correlates with how handsome he is.

Size matters, too. A study released last year by two professors at the University of Florida and University of North Carolina found that tall people earn considerably more money throughout their careers than their shorter co-workers, with each inch adding about $789 a year in pay.
