To many Progressive Era reformers, the extent of street cleanliness was an important gauge for determining whether a city was providing the conditions necessary for impoverished immigrants to attain a state of "decency"--a level of individual well-being and morality that would help ensure a healthy and orderly city. Daniel Eli Burnstein's study examines prominent street sanitation issues in Progressive Era New York City--ranging from garbage strikes to "juvenile cleaning leagues"--to explore how middle-class reformers amassed a cross-class and cross-ethnic base of support for social reform measures to a degree greater than in practically any other period of prosperity in U.S. history. The struggle for enhanced civic sanitation serves as a window for viewing Progressive Era social reformers' attitudes, particularly their emphasis on mutual obligations between the haves and have-nots, and their recognition of the role of negative social and physical conditions in influencing individual behaviors.
