Substantial research shows that high-quality early childhood education programs have a large economic payoff. This payoff is increased earnings for former child participants, increased earnings for parents, and increased earnings for all workers when average worker skills improve. A program package of universal pre-K, combined with child care and parenting support for all low-income families, would cost $80 billion annually. But each dollar invested in this package would yield future economic benefits of over 10 times as great. (author abstract)
