David Rolfe Graeber (/ˈɡreɪbər/; February 12, 1961 – September 2, 2020) was an American anthropologist and anarchist activist. His influential work in economic anthropology, particularly his books Debt: The First 5,000 Years (2011), Bullshit Jobs (2018), and The Dawn of Everything (2021), and his leading role in the Occupy movement, earned him recognition as one of the foremost anthropologists and left-wing thinkers of his time.
I disagree. The native Americans were "technologically" quite advanced when it came to stewardship of the land. Think agriculture (food and forests), language and the like. Europeans basically enacted biological warfare on them.
