The eternal parable

On day, the Mayor drove his executive limo to town. Quite a crowd was attracted so he decided to get off and shake some hands. Words spreaded and more people gathered. Those who came late started to squeeze through from behind. The momentum of the crowd began to push the limo to move forward. The Mayor could not get back in his car because he was tightly surrounded and his voice could only be heard by a few nearby. Seeing that the limo was leaving, more people gathered with more pushing and squeezing because no one wanted to be left behind. The limo thus travelled town after town. The crowd is so hugh now that the limo could not longer been seen. The new comers joined no longer for the Mayor but for sheer curosity and peer attraction. Who is leading? Not the Mayor, not the limo. The momentum of the crowd decides. "There is a cliff ahead, stop!" A few people in the front are crying as loud as they possibly can, while the crowd moves on.
