When you quote $200 to $300K revenue per head, you are quoting averages, whereas the firms I quoted (and also say, Qualcomm) earn have greater revenues per head and Facebook is about $1 million per employee. Google has a 3 million square foot building in Manhattan which they purchased for $2 billion. I'm sorry but I don't see Microsoft, Oracle, Apple, Amazon, or any other tech firm making anywhere near that commitment. Of course, not everyone wants to live in Manhattan and I never said that, but as Google has demonstrated, it should be the second place after SV that you want to have a major presence. There are a lot of extremely intelligent high value employees and networks there. It is also a best place for employees to be that want to improve their careers esp if it overlaps with media, finance, health care delivery, pharma, ... BTW, I don't make my money as a software or hardware engineer but once worked in both fields. I do believe, with the exception of Google, that Goldman and other top tier finance firms have been brighter than many of the SV firms that have only made a small presence in NYC.
