Charles Loring Brace,
The Dangerous Classes of New York…
“ Among the large class of poor and ignorant girls in a large city who are always just on the line between virtue and vice, who can say how many more would be plunged into this abyss of misery by an apparent legal approval or recognition of the offense through a system of license? Among the thousand young men who are under incessant temptations in a city like this, who can say how many are saved by the consciousness that this offense is looked upon both by morality and law as an offense, and is not even recognized as permissible and legal? A city license constitutes a profession of prostitutes. ”
