The answer is not national income (GDP) growth alone. In 1974, Richard Easterlin first documented how happiness did not increase in correspondence with GDP growth. This still holds today. For example, while GDP per capita (adjusted for inflation) has more than doubled in the United States since the early 1970s, happiness has declined. China serves as another example. From 1990 to 2015, GDP per capita increased by a factor of five, yet again, happiness, if anything, declined.https://www.improof.lu/app/uploads/2023/10/crowd.jpg19201076
