Ay Chris! I'm super glad you point out this assumption. I probably could've done some good placing an asterisks in there, one that acknowledges those folks who earn money doing what they enjoy. I mean - I know people who work within their passions, Capitalism definitely allows this. (Sometimes I even consider myself a fortunate enjoy-how-make-money person, sometimes : )
I think I omitted this point because I was trying to outline a Zeitgeist, which is a pretty broad stroke of analysis. I actually have trouble making such broad statements specifically because these omissions tend to occur. Over-simplification; Reductionist. Or maybe just a palette tester? Whatever it is, the question seemed to call for it and so I just went for it.
