I used to consult with several "prepper" groups around the state. They've pretty much all disbanded or people have fallen away. As John mentioned it can be doom and gloom all the time and that can be fatiguing. And as another friend (Howard, a member here.) pointed out, you end up with all this expensive gear that sits there, getting old and unused. Better to have gear/food that you use and as John points out, cycle it out. It's a subtle mindset/lifestyle change, but a significant one.
I may have told the story of a prepper con I went to in Columbia. It was held at a large fairly modern church. I met some of the host and commented on how I thought it was interesting their Church was holding a prepper con. Their reply was, it was their minisrty. They, like other preppers, felt there was some sort of cataclysm about to occur. So, not only did they feel the need to prepare, they felt the need to prepare for others as well. The sick, the elderly, even the healthy that didn't prepare or were unable to prepare. This was an eye opener for me. Prepping is usually a somewhat selfish focused endeavor secretly hoarding and protecting supplies from others. And here was a group openly putting away supplies for others, like David storing grain for the seven years of famine. That changed my thoughts on prepping completely. I started thinking on a much larger scale. Because in reality, I'm not going to shoot the hungry little orphaned kid that comes knocking at the gate.
But, gang of mauraders coming down the road? Well, that's a different story.
ETA - Were in a lull now. Economy is looking somewhat good. People are spending money. It may the calm before the storm. Like the seven years of plenty before the seven years of famine. Now is the time to gather, while it is easy.
Just sayin'
