What does riis state will happen if the slums are not wiped out

Riis stated that if the slums are not decimated, the slums will destroy all citizens.

Explanation:

Jacob August Riis was an American social documentary photographer. He investigated the scandals that capitalism provides and revealed life in the favelas of New York in the late 19th and early 20th centuries. He was a great supporter of photography.

Riis at the turn of the twentieth century recorded the conditions of the people living in the slums in poor living conditions. His series entitled "How the Other Half Lives" catalyzed the social reform movement that culminated in the first housing legislation for apartment buildings, which resulted from Riis' claim that the slums should end. He claimed that if the slums were not decimated and their residents had better housing conditions, the slums would destroy us all.
