Is this what they taught you in school or did you figure it out yourself? Either way, you may want to update yourself on the constitutions of the ~50 countries you're talking about. For starters, there is no "the Governent of Europe". Each country in Europe, even those within the European Union, have their own elected government. By the way, over here the governments are elected by actual majority and not by proxies.
Further, if you do some research on the US constitution, you may even find that most of it can be traced back to France. Sorry.
