I think that there are some factors that favor younger people when it comes to decision making, and some factors that favor older people.

Younger people tend to be more creative and flexible in their thinking. As they get older those tend to diminish, but they gain knowledge and experience. I suspect that until somewhere in middle age the gains from knowledge and experience beat out their thinking becoming less flexible and creative when it comes to making well thought out political decisions.

it's not about decision making, it's about incentives. No one is arguing for a performance based voting algorithm. A young person will eventually have to be an old person, so they must balance the interests of both. An old person will never have to be a young person again though, so they only vote in the interest of themselves.
