The role of bureaucracy is particularly relevant and interesting. Joseph Tainter argues in The Collapse of Complex Societies that the diminishing returns of increasing layers of bureaucracy are an important reason for the collapse of societies:
“Sociopolitical organizations constantly encounter problems that
require increased investment merely to preserve the status quo.
This investment comes in such forms as increasing size of
bureaucracies, increasing specialization of bureaucracies,
cumulative organizational solutions, increasing costs of
legitimizing activities, and increasing costs of internal control
and external defense. All of these must be borne by levying
greater costs on the support population, often to no increased
advantage. As the number and costliness of organizational
investments increases, the proportion of a society's budget
available for investment in future economic growth must decline.”

Quoting from the book:
