@ FIRE4Science - Do you recall posting this 2 years ago, when you were last active here?
"Also, great dividend investing advice comes from Warren Buffet."
Warren Buffet recommends people invest in the S&P 500. Do you think Buffet is wrong, or your new theory that everyone will sell all their assets the moment they hit retirement?
And just to take this in a constructive direction, what happens if someone decides cash is better than investing? What if OP's theory is wrong, and the future is similar to the past?
Withdrawing at 4% for 30 years simulated with Vanguard's nest egg calculator:
60% stocks / 40% bonds has a 91% success rate. You go broke 1 time in 11.
100% cash has a 13% success rate. You go broke 7 times out of 8.
