In to my view, income and the happiness have a collateral relationship. I am sure that many people have different opinions about this topic, but the economy is a critical thing which has an important effect on an individual’s happiness. In our daily life, we see many examples of this. For example, you want to buy a new cell phone and you do not have enough money. I am sure that it would affect your emotion negatively. On the other hand, if you have enough money and can buy it, you would be happy. Secondly, if you are a father who has two children and have responsibilities about your family members' happiness, what would you feel if your children want something and you could not afford it? And it would have a butterfly effect in your family. Someone’s sadness would affect other family members emotions negatively, and you would live in an unhappy family. Lastly, many scholars assert that, people who have an economical power, have a good health. Their bodies emit serotonin which has a good impact on their health.
So wealth is a crucial thing which can not be ignored in determining an individual’s happiness.
