That is true, and fear of that is a valid reason. For some reason, people feel that once they file, their amount is less likely to change due to government involvement. Or at the least, they can’t take back the amounts already given. True enough. But is the likelihood of that greater than a loss be cause of more dependence on your portfolio as you age and can not possibly invest wisely? I don’t have an answer. My personal feeling, at age 60, is that cuts are more unlikely for me in the next 7-8 years. But I can see increased taxation of SS based on income. As mentioned, no choice is bad. One just may turn out to be better historically after the fact. I think the bets are hedged better if one delays until there is a valid reason not to. Not much difference than people stating that it is obvious that once you are retired, you should not be invested in equities. You might lose everything. The ER people here scoff at that. Without equities most could never have ER and stayed ER. So in general, on this forum, there is more confidence with their own ability to preserve and determine their income with funds under their own control. The fact that someone posted that all you have to do is earn a consistent 9% with low inflation to beat the file at age 62, is more acknowledgment that for the long term, filing early is a smaller income for the vast majority. If anyone can consistently earn 9%, or 7% over inflation, then they would be wealthy to the point of laughing at SS amounts as anything to consider. Like most here, I’ve averaged over 9% this last 9 years. I don’t consider myself a good investor.
