Which brings me to JKS's response...
It's not that people in poverty don't care about their city. It's just that the things they care about are not necessarily the same as the concerns of people in more privileged positions. Take architecture, for instance. Architecture is a very class-based interest. It's true that, logically, there's nothing stopping people in poverty from appreciating architecture. However, an interest in architecture is something that people develop over a long period of time, and it is tied to many other lifestyle factors: being able travel, buy a home, shop at high-end furniture stores, or read about history or aesthetic philosophy. These are all things that might lead one to become interested in architecture, and they're also all things that are pretty much unattainable to people suffering under poverty.
