Granted, many studies have confirmed that wealthier nations tend to be happier than poor ones, and that rich people are generally more satisfied than their less affluent fellow citizens. Yet other findings from several relatively well-to-do countries, such as South Korea and the United States, suggest that people there are essentially no happier today than they were 50 years ago, despite a doubling or quadrupling of average per capita income.
没错，许多研究都表明富国的国民要比穷国的幸福感更强，而富人则比其他收入较低的同胞们更有满足感。但针对几个相对富裕国家（比如韩国和美国）的研究也显示，即便这些国家的国民人均收入已经比50年前翻了两番或是三番，但人们却并未觉得更幸福。
