How do the production, trade, and consumption of coffee contribute to global inequality and poverty?

In current Global Coffee market, most companies followed this mechanism:
- Buying the coffee beans from exotic regions such as Emirates Arab, Brazil, Indonesia, etc.
- Adding them with various ingredients
- Resell it to countries all over the world at a significantly higher price.

In this mechanism, the actual producer of the coffee do not even earn 1/4 of the companies in industrialized nations earn, which contribute to the Global inequality.

Americans often speak of their country as one of several large regions.  these regions are cultural units rather than governmental units --  formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share. what makes one region different from another? a region's multicultural heritage as well as distinct demographic characteristics like age and occupation make regions different and special. within several regions, language is used differently and there are strong dialects. there are also differences in outlook and attitude based on geography.
