Ask HN: Have You Ever Lived in the Third World?

I suppose every participant on Hacker News must have Internet access to participate at all. But I'm aware that some of us in our community live right now in countries that have limited economic development, so you have a different perspective on issues from the majority (?) here. I was born and grew up in the United States, and live in the United States now, but thirty years ago I lived in one Third World country (Taiwan), and visited another (China, then much poorer than Taiwan), and that experience has stayed with me as a reality check on my usually American perspective on the world. I'm sure many people here have lived in more than one country, and it would be helpful to know if you have seen the Third World up close.

What has been your experience? Where have you lived that is part of the Third World, or was part of it when you lived there? What can other Hacker News participants learn from daily life in the Third World? What Third World problems are important for hackers to attempt to solve? I'd be delighted to hear what we can learn from your experiences.
