I disagree Marxism may aspire to fully explain all Empires and
Economies for all time but I think dialectical materialism falls very
short once one steps away from the early modern era (Even then does
not capture early modern Europe all that well).
What is 'predatory' here? If you are a Marxist Economic Exploitation
and the position that you seem to be affirming is that culture is
merely the superstructure that justifies and enforces this
exploitation but does not dictate it. I believe one can
argue more easily for this to apply to the 18th-21th centuries, but falls apart
horribly when you look at history before then particularly the Ancient
and Medieval world, I will focus on the occident because I can say I
am ignorant of mesoamerican history.
I think if you told an ancient ruler Marx's famous 'Man is an economic
animal' (as I understand it a play on Aristotles rational animal) the
response would be one of amused contempt and would reply with perhaps
something to point out that man is a warring animal an animal that
wishes to conquer and that the dialectic of history so far as their is
one is of fragment 25 of Heraclitus:
'War is both father and king of all, some he has shown forth as gods
and others as men, some he has made slaves and others free.'
While it might seem that war can be dictated by economy, it is not the
only factor and the question looks more like what economy does for the
empire/city/state in times of war dictates history. That is most
changes in human history where external and due outside antagonism and
if their was a dialectical of this change it's in how the failure of one
allowed the other to conquer the other.
So it is war that dictates history primary that is not reducible to
economy (only a factor). And the desires of wallstreet are far removed from that of Lycurgus and are very different animals.
Tell me where you disagree, I used to have Marxist sympathies but the
more I read the more they dimmed until I realized how many mistakes
where in it. As an aside reading Engels metaphysics is one of the
fastest ways to lose respect for Engels as his writings on metaphysics
are perhaps the worst on the subject to be published of all time.
