Spurred from this post about The Office where I saw some back-and-forth about potential occupation-shaming(?), like why are people getting heated over being able to work?

I understand there's mental health, physical disability, learning disability, or just general lack of opportunity for some people or situations, but shouldn't everyone's drive be to contribute to society as a byproduct of participating in it?

Yeah, capitalism is fucked up, but at the end of the day, shouldn't everyone be motivated to contribute something back to earn their keep? Or can we just say "fuck it" and get mad at people who shame us for choosing not to submit to the 9 to 5?
