I think this is very true, but it's worth pointing out to people. A lot of people don't think it through. You get technical people who are really passionate about their work. Additionally, they want to get rich. They think SV is the perfect marriage -- do amazing technical work and get rewarded with riches. The reality is that the money attracts a lot of people who are completely uninterested in anything but money. It's obvious if you think about it, but many people don't think about it.
