An optimal truth system is one which focuses on the qualitative growth in knowledge, and secondarily the quantitative growth. It is far more important to know what life IS, than what insects reside in the Amazon rain forest. It is far more important to recognize and integrate the idea that our souls and bodies separate at death than to cure cancer or heart disease (and in any event, little progress other than early detection and early intervention has happened over the last half century).
An optimal political system is one which maximizes the number of meaning systems.
An optimal economic system minimizes quantitative pain (cold, hunger, illness) and, by the same stroke, maximizes access to plenty.
Self evidently, you cannot maximize generalized wealth by decreasing it.
