Currency and lesson from the history

Once upon a time, in human history, we used Salt as a currency. People used to exchange things in terms of salt. If you want to buy something, make a salt pile near the merchant, if the merchant likes the size of the salt pile, he will exchange goods for salt. Salt was scarce, because most civilizations were flourishing near rivers, quite away from the Sea.

Some men realized that we can easily produce Salt from the Sea. So this blacksmith, this farmer, and this artist, and this doctor of the ancient times, stopped their profession and started making salt. They were very happy, and thought they are intelligent by so less work, they can get everything they wanted in their small world.

Soon, other men also realized, that it is better to produce salt rather than working. So lot many men stopped produced essential things, everybody was involved in producing salt. Ofcourse, Salt lost value.

Then we used Copper and brass minted coins. Chinese, used Silk as currency. Both ended up at similar fate.

Then came the discovery of Gold and Silver, Silver faced similar fate. But Gold, retained its value, because it was less under the crust of the earth. How much ever men were involved in producing Gold, the hardwork in producing gold was more than the hard-work in producing something which Gold can buy. So Gold never lost value, it prevailed as main currency for thousands of years.

After evolutionary lessons of salt, copper and silk, we finally settled for Gold as currency. Gold was accepted by every civilization. Forgetting the lessons from the history, look at where we are right now, Paper.
