People expect leaders that are:
* strong * fair * capable * intelligent * loyal * available * caring * personal * decisive * on top of things * courageous
People who believe in God see that as a list only God himself could check off. That means we have an innate desire for a leader with the qualities of God himself. To the extent that people try to find perfect leadership in imperfect men and ideas, they will be disappointed. Pick literally any names: Bush, Obama, Trump, Jobs, Gates, Musk -- even Gandhi, Mother Teresa, Dr. King and Thomas Jefferson. So we become disappointed and move on to other people and concepts. Or we find God as He is, not just as we would imagine Him, and find peace in belonging to Him.
In a more personal take, I tend to be hard on my bosses and organizations; at times I have to remind myself to have reasonable expectations for human leaders.
