I think the difference with veganism is that vegans argue that there’s no downside to being vegan (the argument is that vegan food is still tasty, healthy, and affordable) and there’s very few high-income jobs that would be harder to get as a vegan (maybe CEO of Tyson Foods?). In an alternate world where cooking meat-based-meals is one of the highest-paying and highest-status jobs, compromising your ability to do it by refusing to eat meat might be less effective than eating enough meat to stay good at your job while using your free time and income to work for systemic change.
