A moral Philosophy that says that all organisms have evolved to survive and reproduce there own kind. To do this they seek out and do what ever is in there best interest at least in the long run. What they do by seeking what gives the mose pleasure or avoids pain. And that with all the things that do this a dollar value can be placed on it. And that all the morals that a person holdes they should hold only because it will help them make and/or save money.There is a movement to reform all morals on this principle called the economic moral determinism movement.
