Caitlyn Collins is a sociologist and author of " Making Motherhood Work: How Women Manage Careers and Caregiving ." Collins looks into “Work/Family Justice” for parents, especially as more and more women become the breadwinners of their families. Her studies show that mothers in the United States are the most stressed of comparable western cultures and speak more about not having enough time to be with their children. Unlike many European countries, such as Sweden, the United States does not have a national support system for mothers. Collins preveiws her research into societal trends and policy with On Second Thought before her speech at the University of Georgia .
