The last Open Thread was in October 2017, so I thought we were overdue for a new one.
Use this thread to post things that are awesome, but not awesome enough to be full posts. This is also a great place to post if you don't have enough karma to post on the main forum.
Consider giving your post a brief title to improve readability.
Hm, could you link to the place where you're getting these figures? I'm curious :-)
(Or give page numbers if it's a book.)
It's only 145 pages and very interesting imo. Well worth the short read. I love the concept of interventions that pay for themselves. An insecticide treated bed net for 5$ including delivery, on average, pays for itself by preventing malaria and fostering a culture with less societal burden down the road; less hospital costs for the sick, more taxes generated by healthy workers; healthy kids from those parents; etc. An economically virtuous circle.
