What makes places like California vibrant is the entrepreneurial spirit, and that means risking capital on new ventures that could or not work.
In Europe(or Asia) is more like, If I put money you guarantee me that I am getting my money back, if not I will own you for the rest of your live.
You have to prove that you have experience being successful in order to success, but if you were you would not need them in the first place.
So nothing risky or new is made on Europe, if it is,it is bought by American companies like Skype. No risk, so no google, no Amazon, no facebook, no Microsoft, even having probably more educated people.
Kickstarter guaranteeing projects would mean no risk projects, and huge bureaucracy cost.
Today it is my work as a backer to evaluate projects, this is my responsibility, I don't want my big brother to do it for me.
