A girl who is lazy and hates hard work, a girl whose mind is rather feeble, and who is of "subnormal intelligence," as the phrase now goes, or a girl who craves cheap finery and vapid pleasure, is always in danger.

Context

“so to speak, all the girls that come for a long period under their influence, no matter what their race or national origin, remain pure. In every race there are some naturally vicious individuals and some weak individuals who readily succumb under economic pressure. A girl who is lazy and hates hard work, a girl whose mind is rather feeble, and who is of "subnormal intelligence," as the phrase now goes, or a girl who craves cheap finery and vapid pleasure, is always in danger. A high ideal of personal purity is essential. Where the same pressure under the same economic conditions has tenfold the effect on one set of people that it has on another, it is evident that the question of moral standards is even more important than the question of economic standards, very important though this question is.” source
