Fucho I think about this a lot and I appreciate you writing about it. For reference I live in Colombia and even in my small town I talk daily with Venezuelans.

First we must understand that it is not about 'fair' or 'fairness'. Much of our world system is poorly designed and a result more of history than anyone alive today.

The world system may explain why Colombians are relatively better off than Venezuelans today or Venezuelans were relatively better of than Colombians in the 1990's. But it does not explain why rich tropical areas are poorer than northern temperate climates - check out this cultural primer

What I find most important is how to redesign, and I am working through 3 ways, agroforestry systems, education and technology. To me the only answer is to go around the world system and use appropriate technology and design to build ground-up sustainable development. I am working with @quintaesencia to be able to support such efforts.
