instead of withdrawing 4% a year a person could easily find a conservative bond fund that would average about 4% per year ...
there are those who would argue, but in any case the more important point is that the 4% r.o.t. envisions increasing the percentage for inflation, so you begin at 4% withdrawal rate but you do not stay there .
P.S. just for the record I retired in 2013 and the 4% r.o.t. has worked pretty good. I have more in stocks than is recommended but stocks have done OK so that gamble has worked. I have 'tread water' as far as total liquidatable assets , which suggest they will go down later on. But the success of it has meant also I can hold off on SS till 70 in just about any likely scenario .
How many years will it take getting SS at 70 to make up for what you would have had you started at 62 and invested the money?
i saw a guy post elsewhere a very good non mathematical reason for deferring s.s. to age 70. it works best for a guy who for whatever reason is not considering his spouse or his heirs. his reasoning was this: if he delays to age 70 and lives well beyond 70 then he has some extra money for those years which is great. but what if he decided to defer to 70 but he didn't live to age 70? is he pissed off because he didn't get anything? no, he's not pissed off about anything. because he's dead.
Nothing depresses me more than going to a casino on a random weekday and seeing seniors feeding their SS checks into the machines. I won't even go into the Beau Rivage in Biloxi for that reason. There are probably hundreds of them there right now.
even Sanders (the most main stream far left politician) has only talked about raising the salary cap subject to SS.
