To some extent, if you’ve seen one city slum you’ve seen them all.

Agnew’s remark treats urban slums as broadly interchangeable—suggesting that, across different cities, the visible symptoms of concentrated poverty (dilapidated housing, overcrowding, inadequate services, crime, and social marginalization) recur in familiar patterns. The phrasing implies both a claim of experiential authority (“if you’ve seen…”) and a flattening generalization that can be read as dismissive: it risks reducing distinct communities and local histories to a single stereotype. In policy terms, the line can be taken to argue that slums are a systemic national problem rather than isolated local failures—yet it also hints at a technocratic or detached viewpoint that may underplay the specific causes and lived realities of each neighborhood.
