I note that Bronze age societies with full command economies, like Egypt, had far lower slavery rates and better conditions for the working classes than market/semi-market states of the time.
I like Graeber, but I'm gonna need some some additional explanation on that one. Don't know he goes into it in Debt.
This is arguing that slavery in early states, like 5000 years ago lead to markets which are distinct from capitalism which is rule by capitalists.
That said, slavery was one of the forms primitive accumulation took in N. America and so slavery did evolve into capitalism.
Well perhaps it's best to read the source material for yourself and make a judgment from there instead of arguing over snippets of arguments out of context. I think that would better serve a non-ideological material analysis of the subject, no?
