Wall Street Exodus to Silicon Valley Isn't Just About the Money

The Valley also offers finance geeks a less restrictive work culture. "From a Silicon Valley view, New York finance seems like a bunch of people in stuffy offices, dressed in suits, pushing numbers around late into the night," said Gayle Laakmann McDowell, CEO of CareerCup, a firm has advises Fortune 500 tech and finance firms through interviewing and talent acquisition.

"By contrast, Silicon Valley tech companies have casual dress codes, bright and fun office spaces, and they talk about the value of 'work/life balance,'" she said. "Also, they're actually building something new that the employees can show their friends and family."
