On the whole, the GDP of the national economy is positively correlated with happiness. The more per capita income, the happier people are. However, when the GDP per capita exceeds 8000 US dollars, the correlation between happiness and economy is not obvious. According to the famous psychologist Seligman, wealth only has a great impact on happiness when it is scarce, and a particularly poor person will not feel happiness. But when wealth increases to a certain level, the correlation between wealth and happiness is much smaller. Even the top 100 millionaires in the Forbes list with a value of 125 million are only slightly happier than middle-income people.
