In my experience, when a company is growing quickly, customers are abundant, there are more new projects than people to do them, and everybody's stock options go up each year, people tend to be cooperative, energetic, and generally delightful to work with. Once growth slows, promotions & raises stop coming, exciting new projects are scarce resources, and customers don't really care what you do, the office politics gets insufferable. It's like as soon as people run out of worthwhile things to do, they invent oppressive status games to pass the time.
My recollection of middle & high school was similar. When kids are engaged, learning things, able to pursue their interests, and have adequate adult attention, they're cooperative and well-behaved. When they're all corraled into the same track and have to compete for grades & attention, they get nasty.
"So, rather than starting off my research with the deep dive into research papers, think pieces, and news articles that’s all too familiar to me from past endeavors, I decided to embrace lateral thinking."
