While I studied engineering, it was common to get in spats with lefty liberal-arts types, who always brought everything around to talk of class, rich vs. poor, and so on. I mainly read The Economist, the New York Times, the New Yorker, and so on, so I thought this perspective was reductionist and overly simplistic, when reality was much more complex, a mostly net-beneficial process where foul-play was a relatively minor factor.
After graduation, when I started working, I had time to read more history and philosophy, learned more about my own domain of expertise, learned how the professional world worked, and also caught up with much more current events. Turns out I now feel like those critics were more-or-less right all along.
I still have issues with the way some issues were introduced to me originally, but ultimately I was just very reluctant to accept that there was basically a full-on class war I was blissfully ignorant of.
