One remark: Calvin is the boy and Hobbes is a toy tiger, Hobbes doesn't appear in this story.
A girl is surprised because Calvin sells lemonade to 15 dollars a glass.Calvin tells him that he is based on the law of supply and demand.
But Calvin demand a big annual salary , a big profit and Calvin does not care about the health of their consumers. The girl goes home and Calvin says that the girl is a anti-business person who ruin the economy.After Calvin says to his mother: I need to be subsidized.
Calvin plays with the word "demand", "demand" has got two meanings:
1. A noun with economic meaning.
2.And a verb.
Conclusion: you can not do business if you haven't got lower prices. This don't create supply and if there is not supply, there is not demand.
