What is the relationship between happiness and money?

Happiness can be bought with money? Many will say yes. Again, one group said, money has nothing to do with peace of mind, comfort.
There is an argument about this. For a long time. In fact, happiness can be bought with money?
The United States General Social Survey (GSS) recently released the results of a study. It has been said that there is a relationship between money and happiness. The study was performed on 44,000 people since 1972.
The results of the study were published in a journal called Emotion. It says that the happiness of a person over 30 years of age depends on his earnings. From peace of mind to comfort, everything depends on money.
This is one of the longest running studies in the history of the United States. The study was conducted to challenge the proverb that money cannot buy happiness.
Research has captured several levels of happiness. In addition, the relationship between happiness and earning has been reported to be very strong since the last decade.
