<prompt> Human: I had my sister over yesterday for a long-overdue session of setting her up with a retirement account. Shes in her late 20s and confessed that she had never even given a thought to retirement.In the process of figuring out her financial situation and retirement options, I went to look into any sort of employer match program and stumbled across a pay stub. I noticed that she had a 401k payroll deduction and started making phone calls to the plan manager. Long story short, her employer had auto-enrolled her in the 401k with the maximum matched contribution 4 of her income and put the funds into a target date retirement fund appropriate for her age. We got her set up with a username and password, and lo and behold she had over 30,000 already saved for retirement! Didnt even know she had been saving all this time--and half of that was employer contributions.Granted, it sounds like whomever is managing the retirement plan at her company knows what theyre doing with the auto-enroll in a low expense mutual fund at the maximum amount to receive the match, but I think if every company did this itd drastically change the rate of people who are saving for retirement.  <response>: Having 30k in retirement accounts under 30 is pretty awesome. Making money with money is fun.
