I think that the belief that all cultures are equal is usually a mistake based on fuzzy thinking. The underlying thought is that “all cultures have value”, which mutates into “all cultures have equal value in terms of increasing insight into how humans interact with the world and each other” and this gets universalised via a mental shortcut into “all cultures have equal value” and then anyone who questions it gets shouted down. Additionally, cultures are porous, overlapping aggregations of chaotic, abstract and mutating human created concepts which resist analysis almost by definition. Assessing a culture based mainly on its economic expediency seems like a startlingly narrow criteria?
