Why Was Capitalism Not Possible Or Was Not Discovered In Pre-State Societies Like Hunter-Gatherers, Pastoralists Etc?

Capitalism has existed for as long as man has existed, as man has traded value of products and/or services from our great-ape ancestry. Capitalism in its current form is merely a more complex construct of the same trade using money as its remuneration.

Capitalism has evolved along with us, but not for the better.
