My column coming up this Sunday (2/17) covers another aspect of this issue--- our ability to do a "withdrawal of application" and redo our SS benefits at a new and later age provided we return the benefits that have already been paid out. The result is a significant increase in lifetime benefits and income, plus potential tax savings for many. This beats anything offered by the financial services industry cold.
You're clearly a careful reader--- one who follows the informational links I include with my columns. Sadly, your habits are uncommon among Social Security agents, so lots of people will probably have your experience. I had a similar experience when I turned 65 and registered for Medicare benefits. The agent was surprised that I did not want to take SS benefits at the same time.
When I told her that it was not a good financial move for me, she looked incredulous. She talked about the benefit of taking the money now since I didn't know when I was going to die, etc.
A week later I returned and handed her a memo on the topic and a printed copy of the Munnell/Soto paper you mention. She waved it away, saying "You can believe what you want."
That said, we shouldn't be too hard on those who work for Social Security. They work long hours and have to deal with a very complex system with more than 2,000 rules. Most are sincerely trying to get the very best results they can for their clients--- you and me.
Many agents, for instance, are spending a good deal of time dealing with the confusion created by the new program of graduated premiums for Medicare. Since your premium is based on your household income for your most recent tax return, some recent retirees will be hit with premium increases that applied to a one year event such as an employer buyout but don't apply currently.
