Great post by Caplan riffing on a post by Posner about means testing Social Security and medicare. My take is a little different on Social Security, I think that we should eliminate the SS tax give everyone over 65 the same amount as a welfare payment. This would make the program more an insurance plan than a retirement plan. It would be insurance against out living your savings and not having children that are willing and able to help you. It would reduce the burden on the young, who tend to be less wealthy than the elderly, and eliminate the burden on the working poor.
