This article has real "It's just a banana, what could it cost, $10?" energy.
Despite all of the commentary about slavery and the abolitionist movement, saying "just quit your job and be an activist" sounds like they've never read Marx and have no idea about the modern-day trend of wage slavery.
People don't want to work pointless jobs. They're tethered to them, because the alternative is poverty and homelessness in an era where social safety nets are being eroded faster than ever before. The article acknowledges this (barely) by comparing people in this situation to "American Dream" types (i.e. a limited subset of mainly white people) with a house and family and lawn (complete with robot mower) and labradoodle, as if that is the only excusable albatross hung around the worker's neck, while everyone else has nothing to lose.
They fail to acknowledge that the majority of workers are living paycheck to paycheck, precariously standing one major unplanned expense away from disaster. The only people who can quit their "pointless" jobs in the name of "moral ambition" are those who are lucky enough to not need them in the first place.
