The thousands of stories in which a weak beats strong, belong to the same literary category and achieve the same effect: numbing vindictive attitude of those who need to earn money to feed their families.
The story of David and Goliath is one of many stories where someone beats another weak much stronger than him.
Some say that this dramatic structure works well because, basically, everyone wanted to beat dad or mom. The old claim child reappears in every event in which, again, that our story that went painfully subordinates are subjected, crushed by the invincible authority Dad or Mom is repeated.
Of course David and Goliath was the weak character was the character who, despite his huge size and strength, ended up by Little David (musician and some psychologist).
However, what I find most important in this repetition of literary scheme characterized in that the "weak overcomes the strong", is the anesthesia that numbs a vindictive attempt carried out by poor adults responsible for getting the best for their children.
If this man, who has to leave to get supplies for his family, gets drunk with these stories that seduce the point to make you feel triumphant, will surely be unable to conquer the riches trying to conquer before listening to this hypnotic story.
In short: Every time a story shows an uneven fight where the underdog wins, we face a numbing dose of combat capability that the poor should have if they really wanted to leave that condition.
Note: Original in Spanish (without translation by Google): David y Goliat
