I am fully aware of sequence of returns risk. As should every retiree be. As far as RMD's the folks in that situation are not the ones in your first scenario needing 'to make ends meet'. Hence the oddly accurate name starting with 'required'. If they needed the money they wouldnt be needing to make 'required minimum distributions' right? They could also have mitigated them with Roth conversions they had good advice.
But to your larger point, yes there are some that will need to sell right now. I don't suspect that the average fixed income 'needing to make ends meet' getting meals on wheels retiree will be seriously affected by short term market fluctuations as they are typically on SS alone.
Now, certainly some may have to plan appropriately and curb their lifestyle a bit to weather this downturn. Not take a vacation right now etc. But again, they wont fit into your sob story very well. Some may have to delay retirement a bit, for sure.
Now where do we agree? I agree that I do not like the downturn either but, as has always been the case, the market will return to the trajectory it had been on at some point.
