How happy are working parents in the U.S.? Not so much, says a study conducted in 22 countries. The report from the Council on Contemporary Families concluded the U.S. has the largest happiness shortfall among parents compared to folks without children. Parental happiness gaps are related to time, money and energy—factors that are linked to employment. CCF cited several reasons, including the duration and generosity of paid parental leave, the number of annual paid sick and vacation days guaranteed by law and the cost of child care for the average two-year-old as a percent of median wages.
