What are the strength and weaknesses of Agnew's strain theory?

* It has the tendency to focus on lower-class delinquency. * It has neglected all but the most conventional goals (middle-class status and wealth). * IT overlooked barriers to achievement other than social stratification (these might include gender, race, intelligence and many others). * It has found it difficult to explain why some people who experienced strain did not turn to criminal activity. Arguably strain and frustration are experiences by many who continue to conform.
