If people rather not have it thank the robber or the person robbed, they can focus the question: Should the person who didn't want to help, be thanked for their money, if a robber took their money and gave it to them? Does the unwanting to help person deserve any thanks? Going with Robin Hood vs the unappreciative rich person makes the topic more interesting though.
If one wanted to say Robin Hood in the story connects to government, then Robin Hood should be thought of as the legistlative branch, because they are the ones who pass laws that reallocate wealth/income, the way Robin Hood does.
