An explicit theme that can be taken into consideration regarding the tales of the Brothers Grimm in Children's and Household Tales, are the contrast between the social classes and their interactions. At first there is the mistaken appearance that the high-class is superior to the low-class, but always showing that hard and unwanted work rests upon the lower class. The interactions are classical and are seen in both directions. In Rumpelstiltskin and Cinderella tales we see the interaction following the direction from the low-class to the high-class. Otherwise in The Goose Girl, Snow White and King Thrushbeard tales, we have the opposite, where royals are placed in the environment of a more humble life.
The eternal desire of the poor becoming rich is as old as human speech, and as current as the latest technology. The hardships of life caused by the need for hard and daily work - not saying that the rich don’t do it as well - lead to the need for sweetening and a pseudo psychological comfort that the tales of the Brothers Grimm provide, as in Rumpelstiltskin and Cinderella, where ordinary young women become majesty.
One of the noblest characteristic of human being is humility, not in the sense of few resources, but in the absence of selfishness. Much better is when humility arises naturally within the person, but failing that, to be compelled to humility is a great solution. This last scenario is clearly seen in King Thrushbeard tale.
This union between classes, even unique and few, show in a sublime way that human equality should be a priority in people's lives, so that the world may become a better place. All conflicts that mankind has witnessed, witnesses at this very moment and will yet witness, lays in the lack of humility, where selfishness is the poison that slowly kills the planet's inhabitants.
