Inequality and Wealth

The unlinking of Top 1% income from all those below them is simultaneous of another trend which is hard to measure, and often overlooked: increasingly, health and human hapiness have stopped tracking GDP and wealth. Correlation, or causation? Would greater equality lead to higher standard of living? Why? In the 1960's President Kennedy stated that a "rising tide would lift all boats," which was generally true, but something changed in the early 1980's.
