The people working in the bureaucracy chose to be there. Bureaucracies self select for people that are okay with it. I'm sure there's a few who are there to change it from the inside but they are the exception.
You're not going to find a lot of vegans working in a meat packing plant.
> But you are going to find vegans working in a slaughterhouse.
Your first link is the first-person account of a vegan who went undercover to document the abject cruelty that exists in slaughterhouses. The pragmatism was in service of a mission to protect animals by disseminating information on such cruelty rather than the “I need a job.” type of pragmatism. There’s a moral distinction here.
The first link's narrator blew the whistle to industry regulators on practices unethical by non-vegan standards, something that is only possible if you're on the ground. The second link quotes an interview:
> Basically, I'm an animal lover. I don't take any pleasure in what we're doing, but if I can do it as quietly and professionally as possible, then I think we've achieved something.
I was not at all referring to 'the "I need a job" type of pragmatism' (which would not be moral pragmatism for a vegan); rather, doing a job that involves killing animals in such a way that your presence reduces the marginal harm could be seen as defensible to a vegan.
Just wanting something that requires a significant overhaul of how you do things, is not enough.
