Unrestrained greed and cynicism. People don't to go Wall Street to do anything but make money. Way too many people in finance are just about pure greed. People who work in technology love computers, people who design tractors love tractors, journalist love the news, people who work on Broadway love being gay, you know? But, who loves doing financial homework? Nobody really.
I'm sorry for bumping this thread, but this statement is absolutely ignorant and false. I am absolutely passionate about finance. I love investing and business. I love financial modeling and reading about various private equity deals, etc. Most people who end up successful on Wall Street are actually passionate about finance. Most of the Wall Street bigshots (like Henry Kravis, George Soros, etc) are actually interested in what they do. A very significant portion of people who work on Wall Street are there because they are actually interested in finance.
And I should care of this, if you are involved with the exploitation of the working class and poor, through wall street under capitalism. Why should I care, if you were passionate about finance?
