Destruction of the environment is a bad consequence that discredits the economic system that generates it. Here again, it is not a simple matter of averaging. Environmental quality is one of the material dimensions of the standard of living. Thus, we can only say that environmental preservation is an independent value that a good society ought to advance. For people, now alive, this will secure some benefits, but it will also require some sacrifices.
Reciprocity demands that the sacrifices by shared proportionately.
In the modern world, environmentalism is an expression of that value of sacrifice for the future generation. Fifth, the Cooperative Commonwealth idea is liberal or libertarian. That is, violence and coercion are considered bad things in themselves, and an institution that relies on violent coercion, as government does, has to be limited if not eliminated. But it is a value that springs directly from reciprocity. When one person has power over another, when one commands and the other must obey, that is an archtypal violation of the value of reciprocity, and rebellion, the retaliation against the wielder of power, springs from a source deep in human nature.
