Earlier quoted context omitted.
Maybe. This is a tough point. The 'system' obviously sucks but I don't want to skirt personal responsibility. It's the upper-middle class straight white cisgendered male's fault if he doesn't take the time to learn about his privilege. He has the resources, but chooses to ignore it. (Note: I'm not saying the person from the article necessarily fits this description; I'm speaking more generally)
Interestingly people who are upper middle class and devote time and energy to the cause of the poor are often disparaged for that. Terms like "champagne socialist" or "bleeding heart liberal" are invoked. Perhaps it is seen as patronising to the poor because it makes the implication that the poor need the help of upper middle class white people to help them out of their problems?
That doesn't mean "upper middle class white" necessarily, but it does disproportionately seem to affect that group (because otherwise we wouldn't be talking so much about gender, class, race, etc. privilege)
