4) Claims to travel using credit card miles and looking for discounts. Believable.
Maybe for the first trip...but spending $25k/year doesn't rack up too many airline miles for future trips.
In regards to MMM, I'm surprised by the consensus of him in negative terms. I'm a huge fan of his. For me, my life is forever changed for the better from reading his blog.
In my view, MMM is kind of like Dave Ramsey - both have really awesome advise and encouragement to live a thrifty/fiscally sound lifestyle in the here and now, in order to have fiscal independence and strength down the road.
However, MMM's trumpeting of the 4%SWR is just as dangerous as Dave Ramsey's "you can save and assume 12% annual mutual fund returns" - or, perhaps even more dangers than Dave Ramsey. Also, IMO, MMM is more of a snake-oil salesman in his story not quite being a complete picture and adding up (for example, things like his Hawaii vacation where he provided construction labor in exchange for a place to stay - which, as one person pointed out, is in violation of IRS rules and regulations).
MMM has MANY young people on his forum drinking the 4% SWR kook-aid without realizing what exactly is in the brew, and convinced with unshakable faith that anyone can retire on 4% in their 30s on a budget of $12k-$15k/year, and many are locked in on doing just that. But what MMM (and even MMM's wife) have failed in is abusing the 4%SWR references.
Granted, I haven't read MMM's postings or blogs recently and he may have started making correct statements, but for the first, say, 18 months of his site getting up and running, he bandied about the 4% SWR reference and statements of "You, too, can retire in your 30s on just a 4% SWR of whatever budget you want....JUST LIKE I DID" enough to make you sick of hearing it. And when I called his wife out on it in one message thread about the errors of their ways in miseducating people about the 4% SWR, MMM's wife tried to defend it by saying the 4% SWR meant you never have to touch your principal, and someone could retire in their 30s/40s with a 4% SWR and never worry. I pointed out the grave errors in her understanding, but she never replied to my post.
Furthermore, he never points out many serious implications of people calling it quits on a microbudget of $12k-$15k/year with a 4% SWR. With such a tight budget, it doesn't matter how resourceful you are, as you are just 1 health issue away from a potentially MAJOR derailment of your entire retirement plans. Not to mention a plethora of other possible things that could happen to such a tiny budget (car accidents, stuff needing fixed around the house, car maintenance, the list goes on and on). By making people insanely sensitive to ANY fiscal shock, it makes their entire 50+ year retirement like living on eggshells.
Imagine spending 40-50 years of your life, every year/month/week/day, just waiting for the inevitable whammy (or two, or three) that shows up to force you back to work at a moment's notice. Some pollyanas might be fine without a care in the world and simply struggle to find a minimum wage job if they are forced back into the working world at age 45, or 55, and then work the rest of their lives until they are simply physically unable to work anymore (and be subject to whatever nursing home accepts medicare)....but I fear that many of MMM's disciples are blindly following the Pied Piper without realizing that his tune has them walking on an incredibly narrow bridge that is more like a tightrope, where just the slightest unexpected gust of wind will send them falling into the abyss of fiscal calamity, impacting the rest of their lives.
Could they sail through life without issue on their micro budget and a 4% SWR? Sure....but I definitely am not betting money on it.
Some will point out that some people do, in fact, eek out a living on $12-$15k/year....but those are the same people who live in poverty, and are just one accident/incident/unforeseen problem away from bankruptcy (or have already filed for bankruptcy once/twice/multiple times).
