Doug, thanks so much for your well presented comparative overview. Hard-hitting yet so thought provoking. I like the side by side depiction of the 'overlapping' generations. A nice amendment of the graph I first saw in the old, slim "Truth" book form 1968.
The concept of overlapping genrations paves the way for an ongoing series of overlaps which is patently ridiculous, except of course to those who don't think. Meanwhile, which ever way it is argued, the end recedes into the distance.....
