1. It can't 2. Even the worlds worst places do not require prepping. They are just normal places, buy way shittier and more violent. Haiti is awful but you still don't need to stock up on food, you can just walk to a restaurant.
An experiment you can try. Every day for two weeks give a 2 year old a piece of candy, then on the last day show him the candy and then tell him he can't have it. see how understanding he will be. it's a microcosm of human nature.
You will never convince the doomsayers that we aren't mere months from living in a post apocalyptic Mad Max world. Doomsaying is a booming industry.
Actually never gave a timeline, but I'm almost 50 and I do believe I'll see it happen. in the end we all are supposed to get to live the way we want to.
Left wing doomsaying is global warming hysteria, right wing doomsaying is debt collapse and prepping. Everyone has to believe in some sort of apocalypse.
If what you want is a life of endless grueling toil from sunup to sundown just to put a few beans on your makeshift table go for it.
