That wasnt what I asked, I asked what events or laws, and what dates constitute this change in open economies. Which we can then check to see if those dates cause corelation.
As for me, I have stated specifically the correlation, that you will se a close following and correlation between two specific data points: wealth disparity, and percentage below the poverty line over long-periods. I have even provided specific numbers to this effect and a chart at one point (happy to give those again).
Still waiting on yours so we can check the correlations there and compare.
