Hazrat Omar (RA) and today's Muslim rulers

The Muslims all over the world know about Hazrat Omar (RA) who used to go out at night in disguise to get to know about the condition of his countrymen. The other day, Al Jazeera was showing the Prime Minister of Norway, Jens Stoltenberg, driving a taxi cab in disguise. As soon as a customer got into the taxi, the PM in disguise began a conversation with the passenger after exchanging formal greetings and soon got to know the opinion of the people. Most of the passengers who got into the taxi failed to recognise him and some said he looked like their prime minister. Immediately, I thought, this gentleman must have known or heard about Hazrat Omar and how he used to check upon the condition of his countrymen.
It is an irony that there is not one single ruler in the entire Muslim world who has followed the footsteps of Hazrat Omar. On the contrary, they are found to be amassing wealth by means of exploitation.
