At last night's Republican Presidential debate candidate Chris Christie called for means-testing Title II Social Security benefits, comparing them to Food Stamps. He also wanted to increase full retirement age, although he didn't specify how high he wanted to go. In addition, his challenger, Nikki Haley urged changes in cost of living adjustments.
As someone once said, "A program for poor people is a poor program." (By the way, who said that? I don't remember.)
