As someone who's pro-EU, I'd also really like to see major reforms within the organization.
While it contributes enormously to the welfare of the continent, the EU is by design dysfunctional and toothless.
I'm a pessimist, there is so much money behind the forces that want to see the EU fall apart because small individual countries are easier to buy off, I don't see how we can defend against that.
We'll only know what we lost when it's gone, but then it'll be too late.
