Even where economic conditions are bad, girls who are both strong and pure will remain unaffected by temptations to which girls of weak character or lax standards readily yield.

Context

“The economic factor is very far from being the chief factor in inducing girls to go into this dreadful life. As with so many other problems, while there must be governmental action, there must also be strengthening of the average individual character in order to achieve the desired end. Even where economic conditions are bad, girls who are both strong and pure will remain unaffected by temptations to which girls of weak character or lax standards readily yield. Any man who knows the wide variation in the proportions of the different races and nationalities engaged in prostitution must come to the conclusion that it is out of the question to treat economic conditions as the sole conditions or even as the chief conditions that determine this question.” source
