First off, thanks for the reminder Nate.
I'm with Indo-Dude on this one.
Those of us living in industrialized nations in the 21st century have won the "Birth Lottery", IMO.
First, consider "PLACE". People living on the street in San Francisco have it much better than those in Calcutta. Not saying they don't get killed, spit on, etc. but there are a whole lot more resources available "here" than "there".
Second, throw "TIME" into the mix and we should really thank our lucky stars we're living now. The average person living on public assistance in the 21st century has a FAR better standard of living than Dukes & Earls of Europe did in the early Middle Ages.
As for reading books, here are a couple I've recently finished that have reinforced my sense of gratitude. These are certainly not scholarly works by any stretch, but the messages I got from them were worthwhile, IMO.
"The Pillars of the Earth" by Ken Follett. Made me very glad to NOT be living in 13th Century England.
"The Road" by Cormac McCarthy. Setting was some unexplained post-apocalyptic world. Made me appreciate food, water, shelter, warmth and (relative) security.
