The findings, published in journal Public Library of Science ONE, seem to confirm the Easterlin Paradox – that the link between life satisfaction and GDP is more or less flat in richer countries.
　　
　　But the study seemed to go further in suggesting a small drop in life satisfaction once countries go beyond a certain level of prosperity.
　　
　　Based on the findings, residents of wealthier nations such as the Netherlands, Switzerland and Norway should be less content than their UK counterparts because of the higher GDP per person.
　　
　　But a separate UN study published earlier this year found all three countries rank in the top five most satisfied nations, while Britain was ranked in 22nd place.（MailOnline）
