The overpriced junk is wedged into bespoke employer 401k programs that are managed by the brokers. There is usually only one or two low fee options hiding in the list and you have to be savvy to find them. Most employer 401k programs suck because they (custodian) are agreeing to the fund composition based on price to them. If you are lucky you might not end up in John Hancock or Transamerica. Yuck!
