I live in Australia and work in a small company and $100k just isn't enough to entice me to go over to the US to work for Google et al; It isn't that much more than what I make now, plus I get to live close to home. And yes, I can choose to move to US if I want, due to the E-3 visa.
There are a lot of people like you even in the US. Cost of living in California is part of the issue. Tech companies could find the talent for less pay if their workforce was located outside the most expensive areas.
I'm sure there are a lot more people like me.
