Probably no political platitude is more invoked or more ignored than this: let's do it for the kids. Everyone recognizes the moral power of making sacrifices today for our children's well-being tomorrow. That's why most politicians embrace this promise, as Barack Obama has. "We know we have to get spending under control in Washington so that we're not mortgaging our children's future" was a favorite campaign line. Just last week, in an interview with The Washington Post, Obama again promised to overhaul "entitlements." But alas, politicians don't always practice what they preach.
