They're not doing "salary math."
When people break down their earnings by the hour, they derive less happiness from pleasurable experiences, found a study at the University of Toronto. (Participants reported that even pastimes like browsing the Web or listening to music weren't as enjoyable after thinking about their hourly wage.)
