“A study of attorneys found that the attorneys whose pictures were judged independently to be the better-looking ones were able to earn about 12% more per year than the less good-looking ones. The better-looking attorneys worked longer hours, but even when that and dozens of other variables were controlled for, the better-looking attorneys were able to bill significantly more per hour. Needless to say, the male attorneys were ranked as much less attractive than the women, increasing the gap in women’s pay over men’s. The bigger the gap in looks, the bigger was the gap in pay. The more time passed, the more the gap widened. Sometimes life isn’t fair.”
