Before leaving for a weekend getaway, President Barack Obama announced details of a plan to make high-quality preschool available to all American children. It would use federal money to make preschool classes available for more low- and moderate-income children. But the goal would be to persuade states to offer preschool to all who wanted it. The program could cost as much as $10 billion a year — nearly a tenth of the entire federal education budget. Supporters say it would provide long-term benefits to all American children. Critics are concerned about the scope of the program, its quality controls and the criteria for participation. Diane and her guests discuss the president’s plan for universal preschool.
