It's already one of the country with the most obstacles when you want to create a business: there are laws at basically every "level of power" and because it's one of the most socialist country of the planet (despite them always saying neo-liberal are supposedly in power) there are a great many level of powers. It's mad. Consider yourself lucky if you want to start a technology startup: it's relatively "easy" compared to, say, wanting to create a factory.
Why are there no french Google, FaceBook, Oracle, IBM, Microsoft, Amazon, eBay, etc.?
And the people defending these socialists are intellectually dishonest: we're assisting at the utter failure of the nanny-state (think socialist Greece and socialist Spain that skyrocketed the debt and drove the country into the wall) and yet the socialist manage (by propaganda, being basically in control of both written and televisualized press) to make believe it's all the fault of the liberals.
This is sick. Just sick.
Now I'm fighting teeth and nails to get my point across: if you're a french entrepreneur, do like me: leave your country. We're in a world where, thankfully, people are still free to move. So move while you can. Incorporate your startup in Luxembourg (like Skype did). Incorporate in Switzerland.
Flee France. That country doesn't deserves you nor the future wealth you're going to create.
