Why didn't you read it as implicitly critical of modern managment? since slavery is almost universally agreed-upon to be wrong, any comparison of an institution to it is more likely to be a scathing criticism against the institution than a praise for slavery or any of its practitioners. Edit : Considering that the author has written a book called "How To Manage Your Slaves" about Roman slave managment satirically in the style of modern self-help books, it's almost certain my interpretation above is a more correct lens to view his comparisons.
