The thing is any form of youth panel will have their hands tied by the "bigger" panel. They won't be taken very seriously so they'll be stuck with a crappy budget and very little freedom of decision.
It would be like being the Student Council's president. You are not capable of really changing the school's way of life. If I was president and I wanted the school to invest more into say the sports programs instead of the music one, my superiors will just tell me to shut up or I'll be kicked out. If I want things to change in the cafeteria then they'll just turn me down again and tell me to shut up.
It's the same thing. It won't have any form of power.
