In my last year on Wall Street my bonus was $3.6 million - and I was angry because it wasn't big enough. I was 30 years old, had no children to raise, no debts to pay, no philanthropic goal in mind. I wanted more money for exactly the same reason an alcoholic needs another drink: I was addicted. It was actually my absurdly wealthy bosses who helped me see the limitations of unlimited wealth. I was in a meeting with one of them, and a few other traders, and they were talking about the new hedge-fund regulations. Most everyone on Wall Street thought they were a bad idea. But isn't it better for the system as a whole?" I asked. The room went quiet, and my boss shot me a withering look. I remember his saying, "I don't have the brain capacity to think about the system as a whole. All I'm concerned with is how this affects our company." I felt as if I'd been punched in the gut. He was afraid of losing money, despite all that he had. From that moment on, I started to see Wall Street with new eyes. I noticed the vitriol that traders directed at the government for limiting bonuses after the crash. I heard the fury in their voices at the mention of higher taxes. These traders despised anything or anyone that threatened their bonuses. Wealth addiction was described by the late sociologist and playwright Philip Slater in a 1980 book, but addiction researchers have paid the concept little attention. Like alcoholics driving drunk, wealth addiction imperils everyone. Wealth addicts are, more than anybody, specifically responsible for the ever widening rift that is tearing apart our once great country.
