According to my perspective income and the happiness have a collateral relationship with each other. 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 daily life we see many examples about it. 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, and on the other hand if you had enough money and could buy it, you would be happy. Secondly, you think that you are a father who has two children and you have responsibilities about your family member’s 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 a unhappy family. Lastly, many scholars assert that, some people who have an economical power, have a good health. Their bodies emit sereton who has good impact on their health. So that happiness has a crucial thing which can not be ignored in individual’s happiness.
