Not necessarily. $40k for two people is doable, it just flies in the face of conventional thinking so there is a knee-jerk reaction that it's insane. Pete Adney has been doing it for years on about $25k with a dependent child no less. As far as early withdrawal penalties, there are a billion loopholes for accessing retirement accounts prior to that age but that's a much longer post. Healthcare is a valid point, however Obamacare has made that a much less stressful proposition than before. You can remove a lot of that burden by taking care of yourself - before anyone says it, yes, I know bad things happen to people who do good things and your uncle ran 5 miles a day and still got cancer. I get it. The odds are tipped heavily in your favor if you do those things, though. His example of the $40k wasn't meant to be taken literally, he just used it because it worked with round numbers and utilized the 4% rule with a nice round $1mm. His point is still valid - the math behind retirement isn't as complicated as we're led to believe. $3 million by age 60 is extremely attainable for two working people on modest incomes. And it's most likely beyond what anyone would need and still enjoy themselves quite a bit.
