Naturally he has no strong sense of property rights. He has always had a hard time to get enough to eat and wear, and he has grown up unconsciously to see the inequality of distribution and to believe that it is not fair and that there is little or no justice in the world. As a child he learned to get things the best way he could, and to think nothing about it. In short, his life, like all other lives, moves along the lines of least resistance. He soon comes to feel that the police are his natural enemies and his chief business is to keep from getting caught. Inevitably he is brought into the Juvenile Court. He may be reprimanded at first. He comes again and is placed on probation. The next time he goes to a Juvenile Prison where he can learn all the things he has not found out before. He is known to the police, known to the Court, known to the neighbors. His status is fixed. When released from prison, he takes his old heredity back into his old environment. It is the easiest to him, for he has learned to make his adjustments to this environment. From fifteen to twenty-five years of age, he has the added burden of adolescence, the trying time in a boy's life when sex feelings are developing, when he is passing from childhood to manhood. This is a very difficult time at best to the type of boy from which a criminal grows; he meets it without preparation or instruction. What he knows he learns from others like himself. He gets weird, fantastic, neurotic ideas, which only add to his natural wonderment. Every person who has not inherited property must live by some trade or calling. Very few people in jail or out choose their profession. Even if one selects his profession it does not follow that he has chosen the calling for which he is best adapted. So far as a person can and does follow his desires, he generally means to choose the calling which will bring him the greatest amount of return for the least exertion. He may have strong inclinations in certain directions, as, for instance, to paint or to write or to investigate or to philosophize, but, as a rule, he does not make his living from following these ambitions. If he does, it is generally a poor living. But usually his aim is to make money at something else so that he can give free rein to his real ambitions. Most men start to make a living as boys from the ages of fifteen to eighteen. They have no idea of what they ought to do or even of what they want to do. Usually, so far as they have an ambition, it is to do something more or less spectacular that seems to have an element of adventure and not too disagreeable or hard; something like the work of a policeman, a chauffeur, or an employee in a garage. Still, first and last, most boys and most men have no opportunity for choosing an occupation. In fact, the boy is told that he is a man and must get a job long before he knows that he is a man or begins to feel responsibilities, while he still has all the emotions and dreams of a boy.
