Well, the question was what anarchists thought of "hierarchy," and, outside of the an-cap movement, anarchists have generally thought rather unkind things about it. It probably isn't just a matter of semantics whether or not I am "subordinate" or just one of two equal contractees in a voluntary association, particularly as you expect bosses to be, well, bossy, on the basis of owning means of production, and nobody to see anything at all amiss with that. That you don't (or perhaps can't) see how significantly you differ from other individualists is telling. Your support for unlimited absentee ownership is duly noted (again).
