Recently I had asked the value of life. Now I wish to clarify.?

Discussions have been made which suggest that certain individuals have a greater value than others, for instance doctors over ditch diggers or tech support for a major computer conglomerate over a dry cleaners staff. When thinking of the social economic and political standing of our world, do you believe that any one persons value is greater than one others? Case in point, a wealthy persons life threatening situation over a poorer person. In our society the wealthy are always allowed to receive the best care, the poorer not. If all life is just as valuable as another then why is this concept viewed acceptable?
