Yeah well Germany, Sweden, Switzerland and Norway are all socialist and I don't see business fleeing from there.
Socialism is so aweful in places like France and Italy because they have such a class stratified and "crush the weak" mentality of fuedal assholes owning everything that when the socialists come in they go way the fuck overboard and the rich see the writing on the wall and panic in anticipation.
The rich in France deserve what's coming to them, and what happens there is has nothing to do with socialism in any other country.
