The are common citizens just like us till they are elected. Once elected, even to meet them, we need to take appointments. They try to hide themselves from the public and think they belong to another super category of people but once elections are announced, they come begging to us for votes again and shameless that most of us age, even if they have done nothing, we vote for them and elect them again.

That is why somebody has said all are equal but some are above equal

Coz they simply are not common citizen.

Because they dont want to be treated like common citizens.

It is mistake of common citizens
CALIPH ABU BAKR'S FIRST ADDRESS

After giving praise and thanks to Allah (The One True God), Abu Bakr (ra) addressed the Muslims gathered at the Prophets mosque:

"I have been given the authority over you, and I am not the best of you. If I do well, help me; and if I do wrong, set me right. Sincere regard for truth is loyalty and disregard for truth is treachery. The weak amongst you shall be strong with me until I have secured his rights, if God will; and the strong amongst you shall be weak with me until I have wrested from him the rights of others, if God will. Obey me so long as I obey God and His Messenger (Muhammad, pbuh). But if I disobey God and His Messenger, ye owe me no obedience. Arise for your prayer, God have mercy upon you."
