Have you worked in these fields? Do you know the first thing about how these workplaces operate? Your comments here mix a Pollyanna naiveté about their day to day operations - both the idea that they are not a grind akin to other fields, and the notion that there might be management to complain to - with a rather merciless, libertarian imagining that "smart people" will naturally "rise to the top", and so will accept "years of working for an ogre" as the basic price of that.
In reality, it's more like ogres rise to the top and then become ogres to other people, and other folks leave the field because they can't handle working with those ogres, but sometimes people luck out and find a workplace that is built on ethical and humane treatment of employees. I wish there was a simple word that could describe that cycle of dysfunction and abuse.
