The fact that Brussels has attracted a highly dubious breed of politician and bureaucrat certainly hasn’t helped, and still doesn’t. But it’s not the core problem. The core is that there never was a mechanism to reconcile the 20% differences, which means we’re fast on our way to 30% and more. Nothing anybody can do about that other than to leave the union.
The EU was founded on ideals of peace. But unless someone does something, fast, it will be the source of bitter and bloody fighting. Better wisen up now, guys (and I don’t mean the leadership, they’ll go on till the end). In math, there are things that just don’t add up. This is one of them.
