Final answer:
The potlatch is a cultural adaptation and not an example of irrational wasteful behavior as argued by Christian missionaries and classic economic theory.
Step-by-step explanation:
The statement is true. An anthropological analysis of the potlatch shows that it is a cultural adaptation to alternating periods of local abundance and shortage. Contrary to what Christian missionaries and proponents of classic economic theory argued, the potlatch is not an example of irrational wasteful behavior. Rather, it served as a way for individuals to demonstrate their wealth and power through the act of giving away gifts and resource.
