Yep, and IIRC Buffet suggested S&P for wife's investments. His research-heavy investment, and ideas around stock-picking, seems to be how he wants to spend his time.

So, if trying to steer people away from obsessing about growing/hoarding more money than they'll ever need... maybe just steer away from Buffet altogether, and towards Bogle.

(Bogleheads can also become a time-consuming activity, but more likely to instill the message of just stuffing it in total-market index funds, keep it boring, and don't think about it.)
