Through a turn of events a few years back, having met the husband of "Dear Abby" through a completely unrelated forum, I ended up traveling through and spending the night in the guest bedroom of Dear Abby's house.
A few things I learned:
Dear Abby employs 3 full time receptionists to read the hundreds of letters she receives daily, who then decide which letters to respond to. The rest, and many other unread, are discarded. She is married to a man that made his own small fortune in a tradesman environment. (Enough such that any of us could retire from it).
They live in a 7200 square foot home. After dinner, I drank a glass of port from a bottle (when I researched the label days later) cost $1,500/bottle. The wine cellar in the home had 6 cases of it. ($100k+ in only a small fraction of the contents of the cellar).
The garage had a vast accumulation of vehicles that made no sense.
The man was retired at age 50+, Abby though did not personally meet her, is similarly aged and still "working".
Though I was treated very well during the 18 hours or so spent at the home, I found their lifestyle to be largely exuberant, and not in line with the middle class America that writes into Dear Abby's column. It's not hard to extrapolate that the advice given wouldn't fall in line with the Mustachian beliefs either.
