"Originally, it was invented as a piece of social technology."
That comment refers to money. It's the lead-in to a new documentary, called Money and Life, that asks some interesting questions. The film opens next week. You can find out when it's playing near you at the website.
I'm looking forward to what the movie has to say - questioning the fundamental role of money in our lives goes even deeper beneath the surface of the "wither philanthropy?" question I've been asking all these years.
Thanks to @philanthrogeek for telling me about it.
