You ask a kidizen why are presidents impeached? They will have an answer – not a political one, but an intelligent one based on the very basic understanding that they have acquired in their experiential journey as a mayor, governor or the top political leader of the society they have built!
Our Kidizens learn social responsibility through the consequences of their own actions. They learn early on that leaders are to be held accountable if they act irresponsibly, are not doing things in the common interests of their community, or, most importantly, do not act lawfully according to the constitution.
The Kidizens draft laws, and the constitution that governs the actions of everyone living in their society. And if anyone breaks those laws, they have to face the consequences. No one is above law!
