I don't know much about PG except what's been mentioned here, but I do know that I don't come from a privileged background and yet his article still was useful to me in reevaluating my current priorities.

Additionally, I would reiterate that I think this could indeed be applicable to many people. PG's example of a time-waster, "arguing online," could easily be substituted with "watching TV" and then apply to the average household in America. For example, if my dad had done like my mom and tried to reduce bullshit, he wouldn't have been an alcoholic who was either working or watching TV and never spending time with us.
