I think a bit part of Austrians having inhibitions about starting their own businesses is as you say, the mindset. And that's what Amy is attacking with the conference. And it will be good! :)
As much as I hate the school system here, I don't think it plays a big part in it, and is used as an excuse to not trying to take some risk (and there is almost no risk!) -- actually, I find it much riskier to NOT BEING YOUR OWN BOSS. Are those friends of yours willing to be someone else's pawn for all their lives? I'm betting they also often complain about how they don't really enjoy their work (at least lots of my employed friends do that). :)
