the plan to save money in the US is fragile and fails by default.
Strongly disagree. Or, at least, it doesn’t seem to apply to the people you’re marketing this plan to. I won’t go through my expenses, but let’s just say that I’m saving money on a grad student’s salary, and don’t project my annual expenses doing anything more than doubling for the foreseeable future. Except for taxes, pretty much any salary increases for me will go straight to wealth accumulation.
In real terms? Once. I’m not going to speculate on inflation. There are, of course, plausible scenarios in which my expenses increase much further, but they have a pretty low probability at present.

...how frequently?
