Lennie would not survive the Great Depression if George had not taken him under his wing because he has no common sense or quick thinking.  Lennie is not the smartest person, so having George to think for him is the only reason that he has a job. George would not let Lennie carry his own work ticket because he knew that he would lose it. Also, Lennie did not even remember that George was carrying his ticket. When they were in Weed, Lennie went up to a girl and began to stroke her dress and when she moved away he held on to her. The police began a search for Lennie, and without George’s quick thinking Lennie would have been caught he would not have been able to explain why he had done it. After they left Weed, Lennie and George needed to find a new job. George was able to find them a new job very quickly after the incident in Weed happened. During the Great Depression people needed to have quick thinking, intelligence., and common sense, all things that Lennie does not have.
