The story of scientists' independence

When Franklin, an enthusiastic netizen, was 7 years old, adults gave him a lot of money to take a holiday. Franklin is going to use this huge sum to buy some toys in the shop. On the way, he saw a boy whistling proudly. He was completely fascinated by the whistle and exchanged all his money for the boy's whistle. Back home, Franklin proudly blew his whistle around the house, but it disturbed the whole family. After his family knew about his transaction, they told him that he paid four times more than the original price for this whistle, and let him know that the extra money could buy more and better things.
