You don't have to respond, but I do want to echo QinShiHuangsSchlong's point: many hierarchies exist due to necessity or sheer practicality in a way that far supercedes any problems arising from being a hierarchy. For example, horizontally organizing a nuclear power plant is a recipe for disaster, and managing and coordinating the production and logistics chain of sufficiently complex but useful technology like smartphones requires vertical elements to administration.

The fact of this then brings us to the Marxist critique, that hierarchy isn't the problem inherently, but class and the products of class society.
