Most people working on the street will agree with me that the culture is full of people with egos bigger than the size of their brains. Your most trusted comrades at work will not think twice before sticking a knife in your ass.
From working for the last few months and hearing people gossip around the office (you won't believe what people say behind each others back), I have come to the conclusion that if bonuses were not such a huge deal, the guy in the next cube might actually sincerely be interested in your success. We have grown to love money so much that the jungle called wall street creates pariahs from once boisterous and very driven individuals (I have seen very nice people just deciding to quit).
I am not complaining about the culture or anything of the sorts. I knew what I was getting myself into when I signed up and I usually adapt well to most situations; but reflecting on these things sometimes just brings me to the conclusion that shitty bonuses would actually bring the assholes 2 steps down the douchebag ladder.
