Sapiens: A Brief History of Humankind

really interesting book. Yuval is clearly weak on economics and he got Capitalism quite a bit wrong, but other than that I really enjoyed it.

Capitalism is an economic system, yet he compares it to communism which is a political AND an economic system. Capitalism per say is not to blame for much slavery, like he seems to do, that is up to the political and moral-cultural systems that were present at the time.

The critique often made by historians and social scientists, including Yuval Noah Harari, is that certain aspects of early capitalist economies utilized, perpetuated, or were complicit in systems of slavery, particularly in the context of the transatlantic slave trade and colonial plantations.
This critique can be applied to the wheel just as much as capitalism. It's a nonsensical argument. The moral and ethical implications of a tool or system are largely determined by the ways in which they are employed by humans, rather than inherent characteristics of the tools or systems themselves.
