Hi Diane,
With regards to the item you bolded; I wastn't identifying what's wrong with his picture, I was comparing it to mine. For 'me' I would choose lower debt (maybe none, just depends on my situation at the time). So, it's more of a comparison than identifying what is wrong with mortgage debt.
Right now, for example, I carry 180k of debt @ 3.5% because I can make so much more (and have readily available cash) by having 60-180k in a taxable vanguard account.
Thanks for the response Diane, I'm sure others saw the same thing you did in my comment.
