In that statement is inherent the fact that unless you put a dollar figure on an item it does not matters to capitalism. this is not a criticism of capitalism, just that how this works. what needs to happen is that we provide a value assessment for 'common goods' like not polluting the rivers or atmosphere. then and only then capitalism will start to care about them. one way of doing that is to create instruments like carbon taxes which models cost of 'making life worse for everybody' which is currently assumed to be zero.
