Here's another article from the same Fidelity source:
401k balances hit record highs - - MSN Money
It doesn't have the "quadrupled" diversion from the Reuters story.
So, I'm a sucker for data, and couldn't help assembling this table of average contributions by age. The last column includes the employer match, which averages somewhere around 3%.

But, I couldn't stop there. A worker with a constant real dollar income, saving at these rates, earning inflation+6%, and retiring with 4% withdrawals, would generate enough 401k savings to have a replacement rate of:
12% for retirement at 60,
17% for retirement at 65, and
24% for retirement at 70
I don't think anybody's going to be retiring "early" based on that level of saving. OTOH, if these workers also pay for a house while working, and get SS, it should allow "eventual" retirement.
