Fortunately I only need 2 - 3% WR currently, but that assumes inflation stays tame until I get to Medicare and SS.
So I've been thinking a lot about why this topic generates so much
sturm und drang. And I'd like to propose the following model:
1) Some disagreements about withdrawal rates are caused by lack of knowledge on one or both sides, and these discussions then to be highly productive.
2) Some differences in withdrawal rates are caused by differences in tolerance for risk or (perhaps more importantly) tolerance for uncertainty. These discussions are perhaps not as productive, but still seem to be interesting to both sides.
3) Some differences are caused by the sunk cost fallacy and tend to generate the most heated discussion for the least potential benefit.
With both the posters I've had the least productive interactions with on this forum (and EV I certainly don't put you in that camp!), it later emerged that both had worked many many years past when they could have retired and now had assets equal to 40-60x annual spending. When a person has put in those extra years of work, I'd imagine it really feels much better to be able to tell themselves that those extra years of work bought them additional safety and freedom from uncertainty.
So in these conversations, one side felt attacked by people who think they wasted years of their life, and the other side felt attacked by people who are trying to talk them
into wasting years of their lives.
And what is to be gained? If I can convince a newbie who is aiming for a 2% WR that they can be comfortable with a 3.5% or 4% WR I may have helped in a little way to given them a few extra years to pursue whatever gives them happiness or meaning in life. If I convince a person who has already saved 50x their annual expenses that they didn't have to save that much.... it probably doesn't help them at all.
