This is how all technology works. A gadget begins as a junky prototype and then progresses to something that barely works. The ad hoc shelters in slums are upgraded over time, infrastructure is extended, and eventually makeshift services become official. What was once the home of poor hustlers becomes, over the span of generations, the home of rich hustlers. Propagating slums is what cities do, and living in slums is how cities grow. The majority of neighborhoods in almost every modern city are merely successful former slums. The squatter cities of today will become the blue-blood neighborhoods of tomorrow. This is already happening in Rio and Mumbai today.
