Excellent piece there man and a very sensitive topic, I want to add one category of slaves that you did not mention and its currently happening in most parts of Africa and Caribbean...I term it "Economic Slaves", an economic slave is one that accept loans from its masters at ridiculous interest rates, putting him/her self or their people at disadvantage compared to the pairs... we have quite a few of these politician in the Caribbean that go on capital market an accept commercial loans at 12% compared to loans that offered to much more developed countries at 3%. I am not to sure what the data is in Africa but i suspect this is the main reason for the chronic high debt economy similar to most Caribbean countries. In summary, this is probably a post by itself but its an important point to note and one must rally the awareness needed to create capital markets and emancipate ourselves from that economic slavery. Most of the times, these countries gladly take these loans because they are desperately needed and demands of population out-grow the government ability to provide opportunities. I would summarize an say its a modernize form of slavery that we continue to struggle with and with these natural disasters in the Caribbean ultra rich groups would be jumping on board offering these credit facilities to these countries creating a long-term economic disaster.
