That's partly because recent enlargements, though they increased the weight of small EU members, did so by bringing in governments uninterested in such progressive change and populations too cynical to even expect this of them. (I say this as a sad inhabitant of one.)

I do believe that if our governments had been serious about pushing for it, Something Would Have Happened

On an even darker note: if the populations had been more serious about this, they would have forced their governments to be more serous about pushing it. In my view, there is a quality of self-fulfilling prophecy about Scandinavian Euroscepticism.
