VC's tend to be look a person in the eye and judge his (almost always) character. They don't like travelling, so most of their investments are made in the Bay Area.

There are definitely some cultural issues at play also, but fundamentally the reason that the US has such a high proportion of tech giants (which seems to be what you're focusing on) is the low cost of capital caused by the dollar's exorbitant privilege.
