People have also been warning about the next market crash for many years. Finally, one happened because of pandemic, and it's over in a blink of an eye.
I'm still expecting an even bigger crash, but I've learned my lesson against timing the future.
"We don't know when the next pandemic will come, but it will come, and we should be prepared for it" is a perfectly reasonable statement. Any pandemic is likely going to require PPE, PCR testing reagents, BSL labs, etc.
Same thing for recessions; predicting the specific timing of one is difficult. Advocating preparations for one - economic, fiscal, social policies etc. to mitigate, for example - is not a bad idea even if we don't know the timing.
Isn't California due for the big one. Should we be spending now to get everyone out before it hits.
Prepare? Absolutely. I can't speak to the state of California's earthquake preparedness, but there should absolutely be supplies and equipment stationed throughout the state in preparation for it. It is my understanding that San Francisco, for example, has water cisterns throughout the city for fighting fires in such a scenario.
It is dumb not to prepare for disasters we know will happen.
Why is disaster preparedness at all controversial?
Don't try to time the market. Do try to prepare for a crisis.
In all fairness, the US did actually think to create a preparedness strategy, it was just ignored when the time came.
In your market comparison, it would be like having a safety net of cash stashed in case of a market crash, and when the market crashes you spend it all immediately on a new car.
