If there is one industry that is known for issuing surveys, it's the mutual fund industry. Every week, mutual funds and other investment firms issue multiple surveys about investors' attitudes toward savings and preparedness for retirement-aimed at spurring people to save more and at giving financial professionals talking points for their clients.

Last week, for instance, Transamerica revealed that only 23% of women are very confident that they will be able to live a comfortable lifestyle in retirement, unchanged from 2004. AARP reported that 80% of investors in 401(k) plans don't know how much they are paying in investment, administrative and individual fees, or how these fees would impact their savings.
