We don’t need capitalism to have managerial or administrative duties

One argument I've seen against communism online revolves around arguing in favor of "managerial labor" - implying that under a communist system, that type of labor will no longer exist. A pithy expression of this argument is "someone has to write the checks!".

But, managerial labor is different than owning capital. In very small businesses, the owner is the manager, but there's nothing necessary about owning capital to then do managerial duties, and there's nothing necessary about being a manager that involves owning capital.
