I just watched the program and found it somewhat misleading. There are funds that make high yields and charge high fees - for me, although not for most here, the net gain is the most important thing.
There was one totally misleading calculation - how funds dropped due to 2% (I think) expense ratio - but they didn't calculate in the yield on investment, just the expense.
If you have $100k and 2% expense yes, it will cost you $2K a year - but if it yields 7% you net $5K. They left out that last bit.
All in all it didn't impress me, other than to confirm that I was odd because I was looking at Morningstar reports on the funds that were available through my 401K when I worked and finding most of them pathetic. I also told people to max out their 401K contributions but none of them (fairly highly paid IT people) felt they could afford it.
So outlier that I am, I lived on half my salary for years - quite comfortably, I must add - and was able to retire at 62. It's not really early but it was a big improvement over working any longer.
The duh factor is setting in.
