PERHAPS EDWARD L. Glaeser was referring to the pensions of members of Congress when he recommended less government spending on retirement pensions (“The elections predictor,’’ Op-ed, Dec. 30), but Social Security was more likely his target. If one were to review basic facts about Social Security, he or she would find that the average yearly pension is a mere $14,124, but nevertheless the major source of income for most retired Americans. It is virtually the only income for about one-third of retired Americans. Reduced spending on Social Security pensions is simply not a humane or wise economic option, given our consumer spending-based economy.
