Again, for those a generation earlier where pensions is the whole thing (or Federal employees or teachers without much alternatives), this should be the norm.
If you have huge 401ks plus pensions that pay everything, what is your additional money intended for? This sounds I suppose like an attack, but it's a philosophical question that plagues me.
That is a very good question. I cannot speak for others, but for me it can be summed up in the phrase "self-insurance".
First, though I have pension, will receive the maximum SS, and have savings/investments, my planning involvement looking at "if I lose any one of those streams, can I still afford to retire... or even live?".
My Megacorp is in good shape, but we have seen lots of Megacorps in good shape goo bad quickly, and with resulting impact on pension obligations. And though it is insured by the government, the current government financial situation is not something I want to rely upon heavily.
Along those lines, all the talk of SS running out of money, and the current legislation that will cut benefits if nothing is done, does not have me feeling all rosy about this income stream either.
While I am benefiting from the market, part of me does not trust the overall financial outlook. All the interest rate shenanigans, government debt levels, world financial picture, and the next "bubble" - whatever it is - has me wondering if all of this can be sustained. How would people feel and react to a 50% drop in the DOW/S&P 500/NASDAQ indices. We already see how just words and rumors can cause market gyrations, what happens when the next financial crisis hits?
So... I prefer to be an optimist, but I also try to prepare as much as possible. While any "excess stash" I am happy to leave to my kids, I also want to minimize the situation of having to be dependent on anyone else. So if that makes me error on the side of having "too much"... so be it.
