In some ways the third world is ahead of us, using what's at hand, and doing it themselves rather than buying specialized contraptions off the shelf. It would be nice to see more people do that around here, but people who were born into the kind of privilege that we have in the first world generally don't like doing things for themselves when they can spend money instead.
I've always wondered what the third world thinks of our "post/apocalypse films". After all, they've been living in the post apocalypse for a long time. It must seem so incredibly mundane to them.
