As my students would say, really cool! I was looking (eyeball only) to see if the line of best fit remained about the same through the years ... despite some fluctuations, the basic positive (sort of linear) correlation remained. Now, if we achieved what he suggested at the end - greater wealth and more equality - the correlation would automatically weaken, the old "restriction of range" issue, as everyone piles into the upper right quadrant.
