I didn't say unique to, but "essential to." It may also be essential to those other industries, but I have no experience in them.
Sure, shady and disheartening things can happen at any company. However, if that type of negative culture is cultivated at the expense of everything else, it can be jarring even for the most stable individual. I experienced some things that were pretty terrible (and illegal) that gave me pause, but more veteran employees shrugged those things off with cavalier sarcasm. I left because I didn't want to become like them.
