Let's face it, UK never was "full member", for all means. But that's beside the actual point: the German/French euro-skeptics see their countries paying the eastern block a lot of money, sees that same block totally ungrateful about it (ooga booga colonialism), but at the same time don't notice their own employers happy to have such markets at their fingertips - because said markets grab also jobs at their expense, again something the eastern block actively ignores. At the same times the ruling parties everywhere won't touch a running system (even when it's barely running) to not lose their hard won privileges, and the rightwing grows claiming imaginary but heartwarming solutions.
