I think the possibility to "change the world" and make something useful out of your life (and even make some money out of it) appeals to a lot of young people.

I think the possibility to "change the world" and make something useful out of your life (and even make some money out of it) appeals to a lot of young people. It's important to remember that most startups founders/employees have a tech background. I don't think the startup model is being well evangelized in other domains of knowledge. We are now seeing an increasingly number of Designers/Marketers adopting the "culture". But these professions are deeply connected with technology also. Most of my friends with non-tech background don't even know what a startup is, although things seems to be changing.
