George and Lennie planned to own rabbits as part of this american dream. Throughout the book, all Lennie could think about is tending the rabbits.
In the american dream life is good. You have a family, a good job and your own land. This is hard for Lennie and George to have the american dream because it is hard for them to get a job and keep it. Lennie always gets into trouble
Small country house, 10 acre yd. Could be George and Lennie's?
Candy, George, and Lennie agreed Candy could feed the chickens. George and Lennie also know that getting to the American dream is hard and they need candy's money to do it.
In Mice and Men, Lennie is hypothetically asleep when he dreams of the land he and George were going to get. The chances of getting the land were slim and not likely, up until Candy offered to pitch in and include his earnings.
Through the trouble of Weed and the ranch, George and Lennie would (in part) want the easier life of just each other. Lennie would also feel like George owes him the chance to tend the rabbits.
