WASHINGTON -- It takes a worried man to sing a worried song, and in a recent speech that seemed like Larry Summers' swan song, the president's departed economic adviser warned that America is "at risk of a profound demoralization with respect to government." He fears a future in which "an inadequately resourced government performs badly, leading to further demands that it be cut back, exacerbating performance problems, deepening the backlash, and creating a vicious cycle."
