This morning I gave a 90 minute talk to ~70 retired folk at GMU’s lifelong learning institute, on a grand history of primates, foragers, farmers, industry, ems, and future stability. Listen here.

The audience was reasonably sharp and in a jovial mood.  Retired folk were especially able to appreciate the analogy with the human species retiring, though many still think the only reason the rest of us don’t kill retirees and take their stuff, or invade Mexico and take their stuff, is our empathy for them. It is hard for many to appreciate other economic reasons for respecting property rights.
