I'm far less optimistic. I was one of the most vocal and active pro-european-startup activists before I left for San Francisco in 2009. With no capital, I started multiple companies. Some failed, some are still active and now do combined multiple millions of annual revenue (e.g. mjam.net). I started Europe's first YC-inspired accelerator (YEurope) in 2006 and helped put the current global hackerspaces movement into motion so we'd have support infrastructure. Back then I regularly talked to european politicians up to the president level.

The point where I left for San Francisco was when I realized that no one there realizes that there is a causal link between wealth creation and having wealth. They don't know they have a problem, or even should they suspect it, they don't know what causes it.

On a recent trip back I haven't noticed any change in that - so even if they wanted to improve something, they wouldn't know what or how. The economic crisis provides a convenient excuse for all problems, not an incentive to explore what's wrong.

The easiest argument against Europe for startups is sadly on an individual level: Statistics. If you're one of the best - but not the best - entrepreneur in Europe (500 Million People), you know that almost no one more talented than you ever succeeded. And almost no one less talented either. In San Francisco, both people more and less talented succeed all the time.

So statistics. It's far more pretentious to think you're so much better than the best among 500 million, than to think you'll do well among the 8 million in the Bay Area.
