Why should I come to SV? Living standard, taxes, workforce cost, housing... I may get $5m funding, but that would only buy an office and couple of employees for a few years. And if I ever make it, VC and California taxes would eat 90% of my profit.
And do not even let me start on family and children cost and friendliness. Buying $3m house, so homeless guy can expose himself in front of my daughter... :(
Raising funds is not that big deal, there is so much free capital now. New trend is residency in tax heaven (UAE, Singapore, Cyprus) and globally distributed team.
