The greatest sum is when the parts are greatest. There is a lot of work on this. See for example "Distributive Politics and Economic Growth" ( http://ideas.repec.org/a/tpr/qjecon/v109y1994i2p465-90.html ) - while also observing that the presumed objective of economic growth has grown increasingly questioned. If the greatest sum includes not just the financial economy, but also the social and environmental economy, we have to account for social and environmental deficits in our addition (i.e. not sum just financial elements of the economy - for economic growth). Growth itself perhaps should be questioned if it is measured as growth of a part only. Growth in understanding is perhaps the most important growth, and the understanding of Aikido Activism would shift economic growth to growth in fruition, which first respects the importance of social and environmental economies to link the financial economy more closely with these.
