I don't think many people have an attitude of "we need to recognize built-in advantages, and should call out people who try to play down or hide them" to benefit themselves - it's an attitude and position adopted to try to benefit those without those advantages. E.g. by showing a beneficial side of certain social safety net policies, or the downside of the default position becoming graduating with massive amounts of student debt, etc.

I'm not bitter, I just think that guy is an asshole.
