The era of industrialization was also the age of invention, which spurred technology that in turn required skills not provided by existing educational institutions. In particular, the traditional elite higher education centers could not, or would not, provide the training in the numbers needed for a technical and increasingly global economy. The GI Bill in the United States changed this entirely, making higher education available to 2.2 million veterans returning from WW2: few of these had previously the chance of a university or college education. The economic benefits to the United States were immense. From community college to university, higher education enrollment burgeoned, so that by the new millennium two thirds of high school seniors expected to get a bachelor's degree. Other countries, including Britain, followed suit. Given this it is difficult to understand the impact of C.P. Snow's "Two Cultures" argument about a cultural divide between a tiny cohort of cultural intellectuals and scientists, since at best it was a generation too late to be relevant and at worst focused on an increasingly irrelevant, class-based society.
