Anthropology is a fairy tale?
Explain further. What are your issues with the research you're calling a fairy tale? What makes it unscientific?
Discussion
I don't see the research, you haven't presented anything that specific. I just know the economics science of the mutual benefit of barter as well as trade in the price system, especially in conditions of sound money, and have seen child after child invent trade on their own. Austrian and Chicago school economics illustrate this. Read any introductory price theory/basic economics book.
You're telling me to read a book while you call research you haven't read "fairy tales" ?
Why do you trust economists so much more than anthropologists on the topic of anthropology? (or any topic lol)
Incorrect assumptions. This has little to do with trusting some unverified thing more or less. The deductive elements of economics are guaranteed true on account of the rules of logic. Taken in context, they present an alternative to the simplistic solution of gift-only economies with aspects seldom understood by scientists of other fields in today's culture which disregards economics entirely.
You trust economists because of their incorrect assumptions? Holy heck
