Mr. Kelman has a post at Federal Computer Week suggesting options for a trade: delay the date at which you get social security in order to get higher benefits, such as long term healthcare insurance later. Like, don't take SS until age 80, in order to have an assisted living home covered.
I don't have a dog in this fight since I'm not on SS and I'm paying for long term healthcare insurance from OPM The initial logic is attractive, but it works only for the small subset of people who continue working and/or have enough investment income to retire on, as Mr. Kelman does but most people don't. But just because it doesn't work for many isn't a bit argument for not providing the option. I keep believing computers permit us to be more flexible without much administrative cost.
