Yali asked the author a question:”Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?”
From author’s perspective, this question can be rephrased as follow:
Why did human development proceed at such different rates on different continents?
According to this prologue, the answer may hidden in the period that from 11,000 B.C. to A.D. 1500. During this period, different continent developed different life styles, technologies and political systems. However, why these differences came about and induced inequality?
The author didn’t point out the answer in the article but the clue remind me of the Black Death in Europe. The horrible germ nailed down thousands and millions of population but brought the development on medical field, undermined religion’s authority and power, made a great change on European’s rules of the society and induced economic redistribution. These changes brought European to an efficient modern world, which is the literate industrial society, while other continent were farming societies and hunter-gathered societies. In the following colonization, the inequality were brought to the whole world.
