Robert Heinlein did an interesting thing. He and his wife Virginia wanted to tour the world, but didn't want to do the usual trip, London, Paris, Rome, etc. They decided to tour the Southern hemisphere. Those essays are mind opening.
Heinlein made a point of asking cab drivers to take them to the very poorest part of any given town in order to get a handle on the various economies. Think on that. (This was a guy who fucking loathed the Soviets, went to Moscow and calculated the true city population by observing shipping from his hotel window. His numbers turned out to be accurate. Virginia learned Russian, from listening to records, so as to not get faked out or fucked with on the trip. LOL, those two were extra.)
One of my favorite bits finds them in Paraguay or Uruguay, I forget, and old Bob is angry with the cabbie. The were driven to a part of town with tiny little houses, flowers in the windows, neat gardens, clean roads, zero trash, all that.
"I specifically asked you to take me to the poorest area!"
"Oh senior, these are the poorest people. They are on assistance and are very ashamed."
This was all from Expanded Universe if you're interested in reading more.
