Here is how you change a system: 1 - you replace the people in charge; 2 - if the new people don't change it, you go back to item 1.
It's simply not possible. And look through history. We already went through many systems and in all faced this same issue. The people in charge where replaced multiple times already, because the previous generation died. And it's not always the blood related children who pick up the crown either.
People somehow pressure them out. It is always messy and specific, so, it's pointless to ask for generalities.
> Who takes care of the people in charge not getting corrupt themselves?
Nobody. You follow the steps.
> Who takes care that the most logical action for a leader is not a corrupt one?
I don't understand this question.
Anyway, if you take a look at history, you will see that the only thing that ever solved a rotten top are those steps I outlined. Waiting for the old people to die off is a way of doing it, but quite slow and unbiased; it works much better with societal pressures biasing it towards keeping the more honest people.
lol. then give an example. If my argumentation is true this should basically never happen.
That's charming.
People have great appreciation of "it was a wonderful little scheme but it doesn't work nowdays".
What's really charming to them is your cynicism, it's what they invested in.
Never underestimate several milenia of human history.

If only.
And that if society is no longer governed by laws, it quickly falls apart. Indeed, societal failure is no stranger in a course of history than beehive colony failure.
