I moved into the corporate world recently and have had the exact same experience. I go there to get my job done and go home to my hobbies, friends, family, etc. They go there to pretend that the job is their passion, gossip about others, sabotage others' careers, make fake friends, avoid their families, and work all day so that they can tell others that they worked all day, even if they didn't accomplish anything.
In a way, I think the corporate world is ideal for people who lack ambition and, as Viva said, like to be dominated. You can make sooo much more money doing private consulting or starting one's own business, but that's hard. The corporate world gives you a clear path to success and asks only that you play their dumb corporate game to succeed. Autonomy and critical thinking are scary for a lot of people.
Luckily, my boss has rhe same attitude I do, so he genuinely only cares that I get my work done. Still, the environment is unbearable. I'm with you, TS.
