I don't know what prehistoric farming skills have to do with the development of "inequality" in people.
Inequality exist because people are NOT equal. Now opportunity should be equal. Certainly too I am not speaking of systemic racial inequalities. I'm simply mimicking Jefferson's belief that there is a "natural aristocracy"
By the way...I'm about 5 or 6 notches below "peasant". :o)
I left that in the quote because I had exactly the same reaction. Shows the systemic drivel spoonfed in a "well-rounded" education.
