As a result of the diversity, we must find some terminology which is commonly understood across Europe. The term "subsidiarity" is eurospeak, but it is understood by the parliaments and governments across Europe, so it is common coinage at that level. Perhaps the problem relates to the lack of usage of the term in our own political discourse. If we had more discussion about subsidiarity between local authorities and national government, perhaps people would immediately understand the issues. Developing and deepening our political discourse on how power is exercised is essential.
