My friend of 20+ years once complained that it wasn't fair that I made more money than her, despite that I was a professional and she was a part-time daycare worker. I felt so bad for awhile after that, until my sister reminded me that we both grew up in the same neighbourhood, and had the same opportunities. Except that my immigrant parents moved to that neighbourhood by working hard, after coming to Canada with $400 to their name; while my friend grew up "learning how to paddle." So, meh.
