An interesting analysis of current worldwide phenomena that many have been somewhat aware of. This article, however, supplies data that supports fears of Americans of important changes. It brought to mind the 1964 release of Bob Dylan, “The Times They Are A-Changing”. The last verse of which is
“The line it is drawn
The curse it is cast

As the present now
Will later be past
The order is
Rapidly fadin'.
And the first one now
Will later be last
For the times they are a-changin'.
