The world, comprising every human, is full of emotions, whether negative or positive. No matter how good the world becomes, there will always be both bad and good emotions. Imagine if we were to trade these emotions in exchange for money anytime we wanted to buy something; I feel it would make the world a safer place.
Emotions differ from person to person. While some individuals have them in excess, others experience them in a very difficult manner. Some people are easily moved to tears whenever they are touched deep down in their hearts, while others are very tough in exhibiting soft emotions, making them appear as if they are emotionless.
Assuming emotions like joy and happiness are the most valued currency, while anger and hatred are the least valued, people who possess emotions such as joy and happiness in large quantities will have greater purchasing power, and those who are always angry will be able to buy fewer things.
This would go a long way in restructuring our lifestyles. People who are always angry would find ways to cut down or possibly do away with their bitter lifestyle because they would want to buy things and compete with the joyful ones.
With this, it would be just like the typical differences we have today between the poor and the rich. The poor are always pushing very hard to escape poverty, while the rich are always on track to remain rich.
With joy being the higher currency, even if it means faking it, people would learn and probably fake it into their lives until they truly learn to be joyful. In the end, the world would become a very peaceful and joyful place.
Using myself as an example, I think I would be among the rich because being happy and joyful is what I’m always fond of. I would buy a lot of things and sell them to the bitter ones at higher prices and become very rich as well.
