I am not the world's best board historian, but as I remember most negative forecasts or reports of negative forecasts have been riduculed all along.
I believe that Firecalc and also the whole (doubtful) SWR idea have made people focus almost exclusively on the market value of their holdings, instead of the earning and dividend power of the portfolio. So a fall in market value implies a lower standard of living, and people who are very eager to leave work do not like this.
This focus on market values is suboptimal, unless one plans to annuitize. Building a retirement on a total return liquidating model is very risky, and will every now and then create havoc.
Platitudes are also very popular, such as "never bet against America". As if America or any other process were an unchanging stable value for all eternity. America today is completely different from America 150 or 100 or 50 years ago, as is most of the rest of the world and the world's competitive and economic and geopolitical realities.
