I think the problem is that people are fascinated by schemes that are extreme and highly unbalanced. Even the idea of FIREing… why are so many people obsessed with the idea of retiring early? Why not find a job that isn’t soul sucking and do that? Hey, maybe you get paid less, but maybe you’d have some coworkers you actually like and don’t mind spending time with. You have to be patient with your life to do that, and patience and balance aren’t sexy or exciting, I guess.
In fact, that's probably one of the largest "lifestyle inflations" that happens.
I think most people, definitely myself, find happiness in simplicity. Mindlessly consuming more and more luxury items as you progress in your career seems empty, even if you can afford it. And anyway, I prefer making my own food because it's less wasteful, cheaper, and I can make it how I want it
A tech worker might make $200 a day after taxes. $5 on coffee isn't huge but in NYC etc it's pretty easy to blow $60 a day eating out and $100/day on rent, and that stuff can add up to where you hardly save anything.
For me, it's a question of values. I'd rather live frugally and have more freedom than trade away more of my time to have more stuff and convenience in my life. For others, the balance is different.
But it's much easier for these influencers to use these simple and everyday examples of how to save money.
