Skeptical approaches are certainly more rational than simply believing whatever the internet tells us, but they can be a trap in their own way. The people saying FIRE is not possible fell into such a trap and lost a valuable opportunity to their own cynicism. So there is a type 1 and type 2 error to avoid, and the enshittification of the internet makes such tradeoffs more common.
I'm reminded from a quote from The Dark Knight Rises, of all things. "Maybe it’s time we all stop trying to outsmart the truth and let it have its day."
The truth is somewhere in between naïve and cynical. All these things are true:
-Everyone in the Western World can benefit from rethinking their relationship with consumption
-Virtually everyone in the United States can retire before 65 if they avoid a few major pitfalls and then consistently save a manageable percentage of their income
-FIRE Bloggers are usually well-meaning people who give good advice
-Cost cutting measures like cutting your own hair and wearing clothes until they disintegrate will save you money
-These small dollar things don't really move the needle on retiring early
-Many popular FIRE personalities were 1 percenters during their working career
-The sacrifices they made to retire early would not even be identifiable as sacrifices to anyone making the median US income
-There are financial and non-financial incentives to overplaying the role that frugality played in their path while diminishing the role that a 1 percenter income played
I understand the perspective that getting too cynical makes you miss out on the valuable inspiration that these personalities can provide. But I have a high opinion of people and I think they can hold all these thoughts in their head at once without succumbing to bitterness.
It kind of makes me think of stuff like... thirst trap moms on Instagram. They lost the baby weight super quickly. Good for them. But that's literally their job. I wouldn't want a mom making $38K a year seeing that and thinking it has any relevance to their own life. There are better sources of guidance and inspiration, IMO.
