I think there's a degree of survivorship bias here. Single-leader feudal power structures are common in business because they're the standard model for businesses here, so you have plenty of examples of them being wildly successful. But there are also lots of examples of failed feudally-structured businesses!

Personally I can think of multiple examples of successful co-ops in one of the two industries I work in (games), in part because there is less of a stigma against less-traditional business structures there. Co-ops have successfully built and released wildly successful projects in a repeatable way. I think we simply don't have enough data to decide at scale whether co-ops are inferior to the way we run corporations in the West.
