EU’s function is to create a mechanism to find a common ground but that’s very hard so that’s why EU is has made a name for being slow and ineffective.

Spain and Switzerland or Sweden and Italy would have very, very different understanding on what the state should be able to do and how much involvement they must have because the way they govern their countries and the problems they face are very different.

Spain or Italy would usually be arguing on preserving some traditional way of doing things, Finland and Denmark would attack the issue very pragmatically and have great ideas that can’t possibly work anywhere else and the France and Germany would propose something that would increase their power in the area and the original concerns would be secondary.
