[Laforet]

Ancient Egypt seems to be the exception in history. Such reliable agriculture and continued population concentration around the Nile are very peculiar situations that have no parallels elsewhere.

If Egypt was truly superior, it really should not have been so easily conquered by Ptolemy and then Rome which both had a much less authoritarian society.

The arguement was that it was sustainable, not that it made Egypt superior to all less authoritarian countries everywhere, for all time.
