Yeah, and you oughta see the letter I wrote them about their hopelessly myopic perspective on the matter, and the areas where they royally screwed up or didnt give enough information.
They wrote me back, and one of their editors is going to be talking to me next week about a revision to the article with more information and some different conclusions...
Besides not talking at all about risk adjustment to the various approaches, the article is pitched towards a wage earner, not a retiree. It was the classic error of reducing the situation to the most simplistic "I can make xx% over here over 30 years and it only costs me yy% to fund that arbitrage". Thats fine if thats as complex a situation as you feel comfortable with looking at and if you make all your financial decisions in close set binary and if you can watch your investments bounce around like a rubber ball while your house is on the line without making any changes to your AA.
Wage earners with a 10+ year horizon before retiring oughta have a mortgage and invest as much as they can. Retirees...a lot harder to make the case.
Thanks CFB! DH showed me that article. I read it sad said that CR needs to stick with evaluating toasters. I didn't have the time, inclination, energy or whatever to respond. But it certainly wasn't useful.
