Answer:
Their legend has to be seen in the context of the time.
Explanation:
They were seen by many who were suffering because of the Great Depression and The Dust Bowl as almost a couple of Robin Hood characters.
They liked to make a point of letting local people such as farmers keep their money when robbing banks, and the robbing of banks were seen by many in the areas they were operating, as a blow by ordinary people against the financial institutions which were crippling them.
To what extent this was achieving the American Dream is open to question. They were killers who did not hesitate in killing anyone who threatened their arrest. This is undisputedly the case with Clyde Barrow. There are conflicting arguments as to how much direct involvement Bonnie Parker had in their killing spree.
Certainly the myth of The American dream was reflected in the thousands who turned up at both funerals.
