Inrural and suburban areas, the majority of low-income children havemarried parents. And among Latinos, more than half of children withmarried parents are low income.

The litany of complaints may sound familiar, but the truth is that many things were worse at the start of this century than they are today. Then, thousands of children worked full-time in mines, mills and sweatshops. Most workers labored 10 hours a day, often six days a week, which left them little time or energy for family life.
