You need a decentralized system, where everyone has some power in decisions. Especially over their own lives and situation. People need to learn responsibility over their own lives, and you can not do that if you give this power to some politician or someone else. Personal responsibility has been lost for many people. Systems have replaced it. Politicians are fake responsible for others, while they can not even be responsible for even themselves (Biden is an easy example).

By giving centralized power to a few people, you also have a position that is most wanted by crooks and criminals. Even if people would first choose the "smartest" people as "leaders". These people would quickly be replaced with charlatans and criminals, because they will cheat the system. And they will betray the people. The US is full with such examples.

It also goes in hand with a free flow of constructive information about what decisions mean what to other people. That is also a form of responsibility to both give and get the correct information. This is not what the mainstream does, and they are just working for the criminals. And people also need to learn how to deal with information. Learn how social engineering works, propaganda and astroturfing, and how it is used to create a false sense of reality.

How to deal with the complexity of information and science I have good articles here:
