Opening the door to means testing social security, a program which is already, in its own way, means tested, is really dumb in part because it doesn't actually "save" any money unless you apply it to people who really don't have much other post-retirement income. The point is that most people don't have much post-retirement income, so if you go after enough of them to actually claw some money back you're going to be going after a lot of people who aren't by any measure "rich."
Want to go after wealthy social security recipients? Increase the tax on unearned income.
