Very true - it's really quite annoying and unnecessary. Funnily enough, even when ex-employees from such firms establish a start up, much of this culture comes with them. I know I had elements of it engrained in my psyche, much to my detriment. It took a good 6 months to train myself to not feel threatened by my own employees. I like to think I'm mostly rid of this mentality now and can celebrate/cultivate the strengths of my team!
