You do realize that I wasn't commenting on the average farmer that just lost everything; I'm not even talking about the average US citizens. I'm specifically talk about us that we save 30-80% of our income, often still have room to spend less, and have invested 5-7 digits sum in index funds, bonds, individual shares, or whatever.
*We* don't have to worry about the market crashing. With our high saving rates we don't need to touch our savings even if 50% of our income vanishes. We (well, many of us) are not debt-laden and desperately need money to pay the next rate. That means it's very likely that we can wait for a year or two until the market goes up, before we even need to think about selling shares.
I've seen so many "this time it's really, really different" and "our situation is completely unprecedented" and never, ever was that the case. Some day I might get surprised that it really happened, but so far there's no evidence that future crashes and booms will be fundamentally different from previous ones.
