I am one of those people who left the Bay Area because of the high cost of starting and maintaining a business there. I am now in Denver/Boulder area. The Bay Area is definitely one of the most expensive places to have a business which is especially tricky when you don't have revenue like most startups. For example, rent for housing has increased dramatically over the last 5 years to point where people with decent jobs need housing assistance. As a business, you need to raise salaries so your employees can keep their standard of living. And employee salaries are the largest expense for software companies. What I think keeps it going is the fact that a lot of rich people live there now and are willing to invest in companies. That investment allows the company to pay its bills while it is building its product. However even with investment, the money still goes quicker than if you were somewhere else. In essence, it looks like an angel investment bubble to me. The question is, will the bubble burst and when?
