Disagree with that since New York is filled with finance and financial tech companies too. Clearly, they're doing something right there and not in Silicon Valley.

It is more likely to be an SV power thing where the nerds finally get to talk to women and only see them as objects.

Women have always been in finance (not limited to Wall St.) as even though trading is glamorous but commercial/retail banking employs a very large number of developers for boring CRUD jobs, as customer service personnel, backoffice and middle-back-office type work.

So women being treated better in the finance sector is more not less likely.
