France is one of the most frustrating countries a young entrepreneur could ever work in. As soon as you find some way to bypass the rigidity of the system to create something new, to make life easier for people and actually create wealth, the octopus grows another arm to strangle you with. It just sucks the energy right out of you...
The UK may have its problems, but it's a breath of fresh air by comparison. It's no wonder 600,000 French people now live in London (and that's just the ones who registered at the embassy).
