Another problem -- some who save don't save agressively enough.
For example, most people in my company are participating in the 401k program because we auto-enroll. However, that auto-enrollment goes into a 1% a year fund. So people tend to feel real secure, because 10% of their annual salary is being saved (6% deduction, 4% match), but there won't be anywhere near enough growth.
Put it this way -- if 1% is good enough to keep up with inflation and I've been driving for 11 years with gas having run about $1.10/gal when I started driving, well, I just want to know where my $1.23/gal gas is now? Because I could really go for that.
I'm not saying people should be buying ultra-high-risk penny stocks, but people are living longer and longer. That takes a lot of money; a lot more than 1% annual growth will get you.
And now I shall step down from my soap box.
Sorry about that, I just worry that some folks have a false sense of security and are going to be caught flat-footed on down the road.
