Here is what I have learned from people who know the system very well and after working with it myself:
- The EU is designed to be influenced and run by lobbies. And it is in the open and assumed.
- The Parliament is a joke. And you can partially blame the member countries who really do not send their best there, because they know it is joke.
- It used to be that corruption was not a thing in the EU. Just because none of those Commission people would risk their career and benefits, and it was severely punished. So they wouldn't even accept a cup of coffee from you.
Now it does seem things got out of control, at least in the Parliament.
