WASHINGTON — State universities and community colleges should offer free tuition to all students who academically qualify for admission. Our current, insufficient, inefficient patchwork of college aid relies increasingly on loans that saddle graduates with too much debt and too few options once they enter the workforce. Tuition-free and loan-free college education would not only give a vital boost to aspiring students of modest and middle means, but make sure we don’t cheat our society of its next great leader because she or he faced a purely economic bar to college admission.
