Timothy J Bartik 
From Preschool to Prosperity 

"The economic benefits of investing in high-quality early childhood education are clear and backed by an impressive amount of research, as laid out in Tim Bartik’s book. With businesses concerned about securing a future skilled workforce, with our military leaders concerned about the future supply of qualified recruits, and with our society concerned about the troubling increase in income inequality, we should be looking at proven investments in children and youth that strengthen our human capital and the future of our economy."-Arthur J.
