I agree, but poking holes in why they're excluded is important, because it let's you have this exchange --

"You can't argue with the math!"

"Well, hold on now, I think you left a whole bunch of things out!"

If you don't know where the problem in the math is, despite there being an extremely obvious problem, many people will ignore your objections. That's why they use math, to paper over their obviously poor behavior.

Being able to strip that bare is useful.

Aye.

It seems to me we'd do better taking an empirical approach and pricing in widespread psychological realities.

For instance, it's clear that one of the things people don't do very well with, especially as they head into middle age and beyond, is big downward adjustments in lifestyle. It just doesn't accord with the expectation of upward mobility and progression through life anywhere, least of all in the land of the American Dream.

So, even when economic circumstances get worse, their spending tends to remain stubbornly high relative to the quantitative reality. It seems to me sanctimoniously chiding people for that is not a constructive response. It's clearly what most people do, in some measure. The question is how to best deal with that systemically, if in any way at all.
