I don't know how it works in France, but in Denmark, we have a capital gains tax of ~50%. However, that only applies if you pull the cash out directly. You can do all sorts of things, such as moving the money into another company, which you then use to make investments from or pull it into a pension fund, both of which gives you a huge tax benefit. So I don't think that part is as prohibitive as it is made out to, although it certainly has some impact. The bigger problems are probably with labour law and general cultural issues.
