What does Schliemann mention as the positive economies of cooperation?

These "positive economies of cooperation" are the various items which lessen the burden of individuals. He has proposed communities in which certain technologies (in this case dishwashers) would omit drudgery and promote the best interests of the group. He also mentions farming techniques, planned communities, agriculture determined by area, specific food supplies for consumption (the elimination of some), and the end of meat consumption (unless people are willing to hunt and clean for themselves). This is a description socialism.
