Researchers compared the growth in countries' GDP over the past 200 years to improvements in the well-being of their people in terms of housing, safety, jobs, community relations and the like. They found that after a certain level of wealth, economic growth eventually outpaces well-being. In the U.S., that divergence happened in the 1980s. In developing countries like Argentina and China, the two measures still track – but show signs of divergence.
