Making generalizations is not my thing but I know two things.
1) A crisis and less jobs means more and more young people here are just saying "fuck it, let's startup my own business".
2) Some French startups have done great and became global players in the last couple years, like Criteo, and there are plenty new and fast growing companies that are recruiting talent not only in France but from all over Europe.
I should know, I work for one such company, it's called Pretty Simple, and its hit social game of investigation is in the top 5 Facebook games. And we're recruiting like crazy (jobs@prettysimplegames.com), from iOS devs to game artists to game designers. We have self-taught people as well as engineers. We're nothing like the outside cliche of France would have you believe, and we're kicking ass with an international team that speaks English interchangeably with French.
Also, Paris is one hell of a cool city to live in, we've got good food, good parties, good benefits, and good people, and living here is not that expensive either when compared to London or the Valley.
