The Simon abundance index

There has been a followup on the famous bet between Julian Simon and Paul Ehrlich on whether the costs of resources go down over time. Ehrlich ("The Population Bomb) thought that Reverend Malthus was right, and we were on the brink of mass starvation. The fact that he was entirely wrong has not had any impact on his dire opinions.

Simon and Ehrlich bet on five materials on a ten-year span.  In this followup, 50 items are tracked from 1980 to 2017. Bottom line, as population grows, access to resources grows.  Simon continues to win.

Now I have to figure out how to put this new learning into ITN.
