I think the OP was talking about the costs of lawsuits and their effects on business, not risk of doing business in general in various places.

Also: I don't think that, in the context of France, the change in presidents is really all that radical. I suppose I could be proven wrong, but I don't see them as being that much further apart than, say, GWB and Obama, even if the latter two are shifted 'rightwards' compared to what the center is in France.
