One of the best lines to support this statement is made at the end of Decker's chapter 6 saying that "culture prevails over all...neither education nor individuation, nor inquiry, nor discipline, are as effective.” (p. 128) Although not directly mentioned. The fact that these are more or less, mainly the educational and discipleship aspects, the things that a normal citizen would have, and that they are clearly not effective means that there is some form of subculture. The last theory has to do with the lifestyle theory. This is mentioned in the textbook as Life Course Theory and is found in chapter 7 of the textbook roughly states that there are factors in your life such as family, school and work which will influence how you act. This is made evident in David's story that he "had his time, learned his lesson and was ready to start again... because of his time locked up…the goals he had successfully internalized were out of his reach” (p. 183) this inability to find a job could force kids into dire situations that could lead them to commit crimes again and get them locked up . This is exactly what the theory says
