I'm curious about this. My experience is that people in my age bracket (early 20s) have been saying "okay boomer" to the people telling us that being in your 20s and 30s is about hustling to show loyalty to your company, showing up at the office five days a week, ingratiating yourself with your boss, spending late nights at the office and being buddy-buddy with all your coworkers. I have never ever witnessed anyone employing this phrase as a response to someone's pessimism about the capitalist society we live in.
Trying to make it about capitalism is also silly. Those rant and rave about that have no alternative to offer. At best they suggest Scandavian style welfare capitalism, which has capitalism right there in the name, but call it socialism because it sounds cooler.
Hot take but I think everyone is allowed to recognize the cutthroat, impersonal nature of corporate hiring and firing and commiserate about it without needing to walk around with a fully-formed proposal for an alternative economic system in their pocket.
I may try out gp's approach with the next adverse code review I get: "While my naming is generic and the code difficult to understand - it is the best solution to date. Stop whining and provide your alternative diff before I can take your criticism seriously"
Really not an alternative diff but a pathway to transition to an alternative codebase built on an alternative development methodology with strong guarantees that said methodology could not yield code that presents problems resembling the ones in your PR.
