Jacob Riis's famous book How the Other Half Lives was written during the Gilded Age. This era in American history saw America grow as a capitalist country producing more goods than any other country in the world. Along with this, there was a growing gap between the richest and poorest Americans during this time.
Riis wanted to expose this problem through his book. In How the Other Half Lives, Riis exposes the unsanitary and unsafe living conditions of industrial workers in New York City. The goal of this book is to raise public awareness and advocate for social reform.
