There is not a big entrepreneurship culture in general (at least in Spain & Southern France) so starting a startup, learning through others experience, next steps etc.. It's harder.

Also the social pressure is a big reason why entrepreneurship is hard. While in USA, failing and starting over is seen as something natural, in the various Spanish and French communities I have lived is seen as a disaster. Even more in some places is seen as an intent of showing everyone that you are smarter than them so you create your own product/service in stead of working in making better the existing ones. I think it's a cultural thing.
