Today is my last day at Goldman Sachs. Over the course of my career I have had the privilege of advising two of the largest hedge funds on the planet [and] five of the largest asset managers in the United States. My clients have a total asset base of more than a trillion dollars. After almost 12 years at the firm ... I believe I have worked here long enough to understand ... its culture, its people and its identity. And I can honestly say that the environment now is as toxic and destructive as I have ever seen it. To put the problem in the simplest terms, the interests of the client continue to be sidelined in the way the firm operates and thinks about making money. Today, if you make enough money for the firm (and are not currently an ax murderer) you will be promoted into a position of influence. What are three quick ways to become a leader? a) Execute on the firm's axes," which is Goldman-speak for persuading your clients to invest in the stocks or other products that we are trying to get rid of because they are not seen as having a lot of potential profit. b) "Hunt Elephants." In English: get your clients -- some of whom are sophisticated, and some of whom aren't -- to trade whatever will bring the biggest profit to Goldman. c) Find yourself sitting in a seat where your job is to trade any illiquid, opaque product with a three-letter acronym. I attend derivatives sales meetings where not one single minute is spent asking questions about how we can help clients. It's purely about how we can make the most possible money off of them.
