To support above argument .I had also like to quote some more example.

1. Kings come and go but the worker / soldier always remain to choose a new King . Example the Pharohs of Egypt have gone from this planet but the Egyptians stays on.

2. New kings are rising in our country who are the gift of their workers. The old kings have all disappeared . New political kings have been born thanks to the working class they represent such as Shri P S Badal /Mulayam singh/ Laloo yadav / Muslim leaders .

Technological Kings such as Sri Naryan Murthy of Infosys.

3. The endangered species of life today in jungle is the tiger who is going extinct every where.

In contrast The trees in jungle will always be there to serve any of the passing king.

Though I feel that this is only one part of story .To leave legacy in time you will have to be a king.
