HIGHER EDUCATION BUBBLE UPDATE: Two-year colleges draw more affluent students. “Comparatively affluent students are picking community colleges over four-year schools in growing numbers, a sign of changing attitudes toward an institution long identified with poorer people. . . . In the lengthening economic downturn, even relatively prosperous families have grown reluctant to borrow for college. Schools are finding that fewer students are willing to pay the full published price of attendance, which tops $55,000 at several private universities. More students are living at home.”
