How much does Lennie and George's relationship rely on utility to be successful as migrant laborers?

Answer: Lennie and George's relationship relies on utility to be successful as migrant laborers because its the only way they can reach for their dreams of owning their own land and home. They aren't related and have different families but due to the fact that Lennie's aunt Clara died, and Lennie is autistic so he cannot survive on his own. He depends on George for his survival.
