Quote from: edthelorax on November 01, 2019, 11:36:48 AMEd, serious question I have pondered for quite some time, When we chart, we assume the measuring tool is constant. If we chart bushel of corn grown per acre per year, we assume the measures, acres, years and bushels do not change. By extrapolation, are we not assuming the value of the dollar does not change when we chart? Because the dollar has been bias to near worthless since coming off the gold standard, are not chart trajectories biased upward? This seems to be burr under the saddle of credibility for me. Thoughts?
