The liquor trade depends on creating and exploiting youthful addiction.

Original passage

Often he is forbidden to sell intoxicants to one who is drunk or who is known to be a confirmed drunkard; but the work of making drunkards of the youth goes steadily forward. Upon the creating of the liquor appetite in the youth the very life of the traffic depends. The youth are led on, step by step, until the liquor habit is established and the thirst is created that at any cost demands satisfaction. Less harmful would it be to grant liquor to the confirmed drunkard, whose ruin, in most cases, is already determined, than to permit the flower of our youth to be lured to destruction through this terrible habit.
