The EU started with noble goals, but given enough time, the purpose of any large bureaucracy shifts to growing even larger and only existing to justify its own existence, rather than serving its original intended purpose.
Remember the "What would you say...you do here?" Bobs from Office Space where workers in useless jobs couldn't explain why their job is needed but they insisted they were needed.
You see this in the corporate world on a daily basis, but government bureaucracies are no different.
