It doesn't make much sense to do logically because you can front-load a lot less at the beginning of your career. It's far better to design a sustainable lifestyle you like when starting out and aggressively fight scaling it up with your income. If you do that the numbers will work themselves out.

On the other hand, rising disposable income is supposed to be a good thing (annuities for lottery winners etc). Cost of living tends to rise with age, too (kids, healthcare...).

That's the lifestyle inflation I'm alluding to. If one can be happy spending X/year 5 years ago, why can't one be happy spending inflation-adjusted X/year today?

Agree about kids and healthcare but those aren't "lifestyle" costs.
