Well, I've been thinking about moving from Vienna to somewhere more competetive for some time (though its not about the money, I'm paid really well here - just about competition, which I happen to enjoy a lot), but the reasons for not doing it are some of the features you get when living in a more "socialist" (though I wouldn't call Austria socialist) country.
Security, low crime rate, very few homeless people, drug addicts etc.. I can basically go to a party, get drunk there and take a walk after that in any part of the city during night without being afraid that some homeless person will attack me. If you ask me, thats a big pro for staying here. Sure, I would probably earn more if I did the same job in San Francisco, but then I would have to deal with a much worse social situation, and I would have to be more cautious.
