A global study led by a researcher at Columbia University Mailman School of Public Health and published in the journal Scientific Reports finds that economic inequality on a social level cannot be explained by bad choices among the poor nor by good decisions among the rich. Poor decisions were the same across all income groups, including for people who have overcome poverty.
It’s more like we have a hundred years of studies that make this point, but it’s always good to test for different causes of inequality to inform policy better.
