FIRE doesn't depend on having a tech job. Its all about income to expense ratio. Planning for medical events is something that gets talked to death in these communities.

A lot of people are often surprised at how non-frugal their lifestyles are. I'm not suggesting that people living on $50k/year aren't already frugal, but yeah, there's definitely people who take out car loans, take out mortgages for the full amount they were approved for, and all sorts of random things like buying chicken parts instead of whole chickens, buying small grocery store containers instead of bulk pricing for shelf-stable items, keeping your speed down to save gas, etc.

You really just need to build an innate understanding that the hedonic treadmill doesn't make you happier long-term and develop a resolution to get your expenses down and stay disciplined about it.

I know several people with normie jobs (not tech related or government) and normie lifestyles that saved up enough money to never need to work again by 50 while still maintaining their lifestyle. Most still work because they have no idea what to do with their time even though they don’t need to work anymore.

You can easily derive that this is possible from the median household finance statistics published by BLS, never mind the upper class. It isn’t that hard if you care to do it.

90%+ chance the person you are replying to has health insurance that will cover them in case of medical disaster.

you don't need to eat ramen. there are many cost effective options out there: oatmeal, beans, rice, you could grow your own fruits and vegetables, etc.

and as for the medical disaster: heart attack and stroke are actually preventable with a plant based diet (keep your LDL under 80 and you'll vastly decrease your chance of a heart attack). i know a lot of people will hate on that, but those are the facts and any evidence based nutritionist can tell you this.
