8. In each experiment there was a competitive struggle between rival communities, each passing through the rural-urban transformation. The result was an increasing conflict for survival, for expansion and for local supremacy.
9. Each experiment expanded along lines that led the more successful to build traditional empires consisting of wealth-power centers and peripheries of associates and dependents.
10. Each experiment produced a competitive survival struggle between rival empires that would determine eventual supremacy.
11. In each experiment one among the local and regional contestants defeated, conquered, dismembered, assimilated or destroyed its rivals and emerged as victor, giving its name to a civilization: Egyptian, Babylonian, Persian, Roman.
12. In each experiment the victims of imperial aggression, conquest, exploitation and assimilation, conspired, united, resisted and revolted against the dominant power. The result was endemic civil war.
13. Within each experiment, as the civilization matured, the same confrontations appeared at the nuclear center and in the provincial-colonial periphery:
a. Extremes of riches side by side with slum-dwelling poverty.
b. Expanding unearned income, with one class (the propertied and privileged) owning for a living and another class (peasants, artisans, serfs, slaves) working for a living.
c. Intensified exploitation of mass labor side by side with the proliferation of parasitism throughout the body social, consisting of individuals and social sub-groups whose contribution in the form of goods produced and services rendered was less than the cost of maintaining the participants.
d. Economic stagnation. Public spending in excess of public income; higher levies and taxes to replenish the empty treasury; rising prices due to excess of demand over supply; public borrowing with no means for repayment; the issue of money without corresponding reserves; degradation of currency through decrease of its metal content; unemployment among citizens due chiefly to increase in forced labor of war captives and other slaves; public insolvency due to territorial over-expansion; excessive overhead costs; nepotism, bribery, corruption in public service; an over-large bureaucracy feeding at the public trough.
