Someone needs to provide the contrarian perspective here.

While Jordan makes many great points (I agree with much of what he said and have recommended The Purpose Code to several people!), a couple counterpoints need to be said:

1) Risk tolerance differs from person to person, and needs to be factored into how safe an option is appropriate for that individual. Based on Jordan's writing, it is obvious that he has a somewhat high risk tolerance for financial security. It is presumptuous to declare that higher risk tolerance is appropriate for everyone. I don't mean 100% guarantees either - it is a sliding scale.

2) While I agree that several layers of backup plans may be paranoid, one or two backup layers is reasonable for someone with a low financial risk tolerance. Historical Safe Withdrawal Rates (SWR) are far from the worst possible case. They just happened to be the worst case seen in the US over a hundred years or so. Most countries have far worse SWRs than the US (the US is not immune to some of those reasons) and Monte Carlo simulations will show higher failure rates than historical backtesting with the same historical dataset (real risk is likely between backtest and Monte Carlo, as "past performance is not a guarantee of future results" but Monte Carlo can generate crazy sequences that are exceedingly unlikely to happen).

Bottom line: Jordan is far more knowledgeable on the psychological considerations (as a Hospice Doctor) but far less on the econometrics (not his expertise, though he does say he is mathematically inclined) needed to determine the econometric risks to an SWR strategy. This post is good food for thought, but shouldn't necessarily be blindly followed by someone with a low financial risk tolerance.

What people really want is control and certainty. They’ll never get it.
