So, after "200,000 years of homo sapians" (according to Pete, I am no authority), we have had maybe 140 years (or maybe more like 40 to be more honest) of no slavery in a small part of the Western World. It still exists in a much larger part of our green earth. Our life since 1865 (or 1965) as an emancipated population is but a blip on the calendar of humanity. The separation of the classes by economics in our world today is to some a prediction of the return to slavery in even the most enlightened societies.
