Lifestyle Creep
Every raise you've ever gotten has mostly disappeared. Here's the mechanism.

The Quiet Drain
You get a raise. Within six months, you're not saving more — you're just spending more. Nicer groceries, faster internet, one streaming subscription that became four. No single purchase feels reckless. The whole pattern is invisible until you look at your savings rate from two years ago and realize it hasn't moved. That's lifestyle creep: spending expanding automatically to consume whatever income rises.
Hedonic Treadmill
Psychologists Philip Brickman and Donald Campbell named this in 1971: hedonic adaptation. Whatever you acquire becomes the new baseline. The mid-range car that felt luxurious is now just your car. The upgrade that felt indulgent is now normal. Your brain resets the reference point upward every time, which means you need the next level just to feel neutral again. Income grows; satisfaction flatlines.
