The real revenue at stake here is the lucrative and often well hidden investment management fees that fund managers charge the employees' 401(k) accounts.

And the article is just plain wrong about the size of most company matches - very few employers provide a 10%+ match to the employees deferral to their 401(k). In most cases it's 3% - 5%, and many companies have cut back.

401(k) plans are great in theory but in reality most workers make way too many mistakes along the way, in not participating fully or even at all, in mistaken investment decisions, unwise loans or withdrawals, etc. and they end up with way too little in their accounts at age 60-65 for a meaningful retirement.
