I worked retail as a teenager, and the managers would give more hours to an older employee because she needed them (I was told this explicitly). I was fine with it at the time, because yeah, I was still mostly living on my parents' dime. Working in a corporate setting now, if I was told someone else at my company was getting a big raise only because they just had another kid or bought a new house, and not due to the quality of his or her work, I'm not sure how I would feel. I guess it just breaks down to whether you think like a capitalist or a communist.
