I think their father left his heritage purposely from Raymond, knowing that Charlie would go to the person who earned his heritage. It was the way he found to join the two sons.
What I really didn’t like in this movie was the end, because it is a very good movie for such as poor end. For me the ideal would Raymond return to the hospital, but after some time the doctors realize that he really felt miss her brother, and they would end up together. Happy end!!
Teacher's note: I have watched Rain Man several times, and I always feel that the ending implies that the brothers will reunite outside Walbrook. And I have always felt a little uncomfortable with the ambiguity of this ending since we never know for sure what the outcome is.
I have never heard the theory that Dad Babbit figured (correctly so) that by giving all the loot to Raymond, Charlie would be greedy and smart enough to find him. In other words, this is Dad's way of bringing the brothers together. It's a good theory! Thanks for an insightful post.
