"The excess consumer demand and jobs created by our credit and housing bubbles have masked not only our weaknesses in manufacturing and other economic fundamentals, but something worse: how far we have fallen behind in K-12 education and how much it is now costing us," wrote columnist and best-selling author Thomas Friedman. Citing a new study titled "The Economic Impact of the Achievement Gap in America's Schools," Friedman warned: "In the 1950s and 1960s, the U.S. dominated the world in K-12 education. We also dominated economically. In the 1970s and 1980s, we still had a lead, albeit smaller, in educating our population through secondary school, and America continued to lead the world economically, albeit with other big economies, like China, closing in. Today, we have fallen behind in both per capita high school graduates and their quality. Consequences to follow."
