Q. How does the power structure easily maintain power?
A. "In politics and sociology, divide and rule (or divide and conquer) is gaining and maintaining power by breaking up larger concentrations of power into pieces that individually have less power than the one implementing the strategy. The concept refers to a strategy that breaks up existing power structures and prevents smaller power groups from linking up.”
This is how the original power structure maintains absolute power, doing practically nothing at all, besides fracturing former allies.
