People go where the money is. It is capitalism. SV is where the money is so people are going to go there. Same as wall street before it. You want the best talent you pay the most money. With Europe paying so little compared to the US I don't know if Crotia or anywhere in europe will be a real tech hotbed.
People have different priorities than just money.
I for one would never move to SV even if I get 3 times the salary there.
There are a lot of other factors that make life great than just money.
Also when those very rich people start buying properties/coast/islands from people who "had different priorities" in couple of decades, the latter will have to rethink their strategy of letting go and not developing their biggest talents. But its going to be too late for that by then.
