“The people implementing something like FIRE are the minority by a wide margin.”
In the aggregate I would agree, yet they seem to dominate the overly popular ‘Personal Finance’ blogosphere. I find it disparaging that the majority of FIRE instigators are, as Carlson pointed out, driven by a “I Hate My Job!” mentality, and dutifully propagate this throughout the land as truth (they are a bit Trumpian, in a way). And almost none will admit, as you just did, that luck played a big part in their success. Messes with the narrative, I guess.
One rather large negative I can see is that these people leave the workforce within a short timeframe (e.g. 10-15 years), thus if all workers did this, there would be no one left to develop and amass the mastery which requires multiple decades of work experience. A dangerous void develops.
(Secondly, isn’t the term ‘financial independence’ a misnomer, in the same league as ‘passive investing’, simply because no financial instrument (or income) is independent. Cash might be the closest thing and ‘financial optionality’ might be a better term.)
But, as you said, those engaging in FIRE are a rather minute fraction of the workforce, thus their impact as a whole is rather moot. And I might even suspect that as time goes on, the ability/methods/instruments for those seeking to achieve FIRE may dwindle (e.g. lower market returns, employment structures, etc.). Thanks.
