And a prescient quote from the article:
...Because of small corporate contributions and subpar investment returns, the average 30-something who does manage to collect from a 401(k) will get less than $400 a month (in 2003 dollars) on turning 67, the institute predicts. The average 70-year-old pensioner today gets more than twice that.
Anyhow, the article makes a pretty nice summation of the current (flawed) system, IMHO. Workers such as those at GM, whom I encounter on a weekly basis, who believe their gilded pension benefits are guaranteed beyond any special circumstance, need only look around to the current situations of some their comrades in other mature and unionized industries (airlines, steel, etc.).
What the company giveth (and the government guaranteeth), the company and government may also taketh away.
When it comes to money, there are very, very few real guarantees.
