Why More?

Curiously enough, a Levi receives more produce than any other Jew. Someone with a field passes on one tenth to the Levi, meaning that eleven tribes tithe one tenth to the Levi. If each produces one hundred units, and gives ten to a Levi, that Levi now has 110 units, or after Trumas Maaser; 91 units, while the others have only 90. Compound that with the fact that the Levi’im were smaller in number, and you can see that each Levi receives more than his fair share. Why ought this be?
One suggestion was that Klal Yisroel received their harvest in the Levi’im’s merit. The Dubna Maggid compared this to a father setting sail with his ten sons to a faraway land. Only one son knew how to cook, but he was lazy and spiteful, and would not cook for others. So the father took along only giant pots, and the lazy son, needing to cook for himself, cooked for them all. So too, Hashem gave the Levi a portion in the bounty of the Jewish people, so that in his merit all received. Indeed, in Levi’s honor Hashem cooks for us all. So it would be no surprise that Levi earns an oversized portion!
I suggested that the farm owner eating his own produce is satisfied with less, because it’s his own fruits he eats. That, in of itself, gives him satisfaction. However the Levi, eating the produce of others, needed a greater portion, for he lacked that satisfaction.
