Money helps you buy happiness

The more money people earn, the happier they are, but when you earn $ 75,000 a year, the feeling of happiness doesn't escalate in money anymore.

To understand the relationship between money and happiness, two researchers Daniel Kahneman (psychologist who won the Nobel Prize) and Angus Deaton of Princeton University in the United States analyzed the results of the survey on the level of happy for more than 450,000 people made by the Gallup organization in the US in 2008 and 2009. The survey participants answered questions about income, health, satisfaction with life and many weaknesses. another factor.

The analytical results show that for people with an annual income of less than 75,000 USD, the more income they earn, the more happy, successful and healthy they are. But for those who earn more than $ 75,000 a year, the level of happiness does not increase with income even though the sense of success and health still increases.

' Increasing income does not affect the feeling of daily happiness in people who earn over 75,000 USD per year, although it still helps them feel life becomes more comfortable ', AP quoted Deaton.

Deaton said that if someone quit a job with a $ 100,000 salary to get a $ 200,000 salary, he felt more successful. But new wages don't increase their sense of happiness in everyday life.

The same trend also occurs for other psychological states. For example, most of us feel happier on the weekends, but our health has not changed even though the mood has become more exciting.

The level of human happiness is determined by many factors - such as the time spent with friends, whether to suffer from illness or not, the number of times a year travels. When annual income increases to a certain level (this level depends on the economic conditions of each country), people no longer have to worry about basic needs so they can take care of their spiritual life. Even so, the time spent with friends, the ability to avoid illness and the number of times that most high-income people travel is still not increasing, so the level of happiness also does not increase.

The research has just been published in the journal Proceedings of the National Academy of Sciences .
