You seem to be reading in specificity that I didn't put there. There aren't any securities that can provide a guaranteed 5% rate of return after inflation, but those kinds of returns are fairly reasonable for a well-diversified portfolio (though they will of course go down from time to time). Maybe a little high, and mea culpa if so, but certainly not high enough to rate a "my ass".

Not really. I think that picking an arbitrary number and compounding it far into the future is a very flawed method of estimating future value -- and that's not just because this number is arbitrary.

My ass was specifically upset about the million dollar figure that the linked-to web page prominently waved about, not about anything in your post.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
