Moses' father-in-law clearly has a great deal of management experience. It is no accident that he is the one who advises Moses to create the first administrative apparatus in the history of the people. One might think that the point here is only Moses' desire to shift part of the burden of governing the people onto others. And that is understandable: why should he personally decide every case and sort out every problem that arises? His task is prophetic ministry; he must be the mediator between God and the people, since the people need a mediator. The rest can be entrusted to others.
In reality, however, everything is more complicated. In addition to easing Moses' own burden, there is also an attempt here to make the people at least somewhat responsible for their own life and their own affairs, because those who rule over the people are chosen by the people themselves. No one chose Moses; he is a leader appointed by God. Any claims can be made against him without taking responsibility for anything: after all, he, Moses, is the initiator of everything he does. God leads him, so let him solve his own and our problems with God while we wait.
Now everything changes: the people choose the new leaders for themselves. Now it will no longer be possible to remove responsibility from oneself completely, because the one who chooses is always responsible for those whom he chooses. Besides, now disobedience to these chosen leaders becomes, at the very least, obviously inconsistent for everyone. First choose elders for yourselves, and then ignore their instructions, not listen to orders, simply disregard them? Any reasonably normal person in such a case would simply stop respecting himself, and those around him would scarcely take him seriously either.
The issue, then, is training in the most elementary responsibility: responsibility connected with authority, with its delegation, and with conscious obedience to those whom one has chosen as leaders. Of course, not everything always goes smoothly here, but people learn from mistakes, and there is no other way to learn responsibility. The people will still have to settle the land promised to them by God, and the experience gained in this way will be very useful there. Without it, no more or less normal life can be arranged on the land given by God.
