The process by which reforms, aid, and institutions built for everyone end up owned by the few who were already on top.
Documented
The development literature's disease
The term runs through World Bank and development economics research: aid programs, decentralization reforms, and participatory budgets repeatedly divert to local elites, school funds become patronage, village committees become family firms. Studies from Indonesia to India measure the leakage directly.
Assessment: Documented: a large empirical literature quantifies capture rates across programs.
Stories
The Ministry of Magic rule
The fictional shorthand the video uses: any institution that protects the elite over reality is already captured, and no amount of benevolent staffing fixes the plumbing. Dumbledore is not a reform; he is a temporary occupant of an un-reformed office.
Assessment: Stories: as political theory it is a cartoon; as a summary of the literature it is uncomfortably accurate.
Interesting claims
Capture as the default state
The formulation the literature circles: perhaps institutions are not occasionally captured but always captured, and 'good governance' is just capture by a coalition broad enough to feel like everyone. The elite never left; sometimes it is large.
Assessment: Interesting: Olson's stationary bandit and Michels's oligarchy both end up here, sixty years early.

Worth asking
Can you design a system the elite cannot capture, or is capture the system finding its owner?
