BTW the Dutch are in a similar position - they are pouring money into the EU and getting very little out - I wouldn't be surprised if they decided they want out too.
And for exactly that reason, the Dutch government will never ask the population for their opinion.
Dutch government ignores the population (and referenda) anyway. Sad but true
Examples: EU constitution, Ukraine-EU treaty
I suppose it is harder for the Netherlands to leave because they were foolish enough to sign up for the euro.
There are two western european countries who pay a lot into the EU who arn't in the euro - denmark and sweden. Both might decide to leave to protect themselves by leaving.
