There is an old folk tale that has been narrated in a children's book, The Little Red Hen. The gist of the plot is as follows
The little red hen finds a grain of wheat, and asks for help from the other farmyard animals (most adaptions feature a pig and a duck) to plant it, but none of them volunteer.
At each later stage (harvest, threshing, milling the wheat into flour, and baking the flour into bread), the hen again asks for help from the other animals, but again she gets no assistance.
Finally, the hen has completed her task, and asks who will help her eat the bread. This time, all the previous non-participants eagerly volunteer. She declines their help, stating that no one aided her in the preparation work. Thus, the hen eats it with her chicks leaving none for anyone else.
The moral of this story is that those who show no willingness to contribute to a product do not deserve to enjoy the product: "if any would not work, neither should he eat.
Obviously, the point of the story is that those who do not work should not get the reward.
