Drob, remember you don't know what you don't know. Pi2 and La Rubia, like myself, are looking at mulitple news sources, Larry Edelson, Richard Martin, Gary Null, even Alex Jones, and if you do that, you'll read and watch some pretty unbelievable possibilities about the U.S dollar falling, even crashing. And of the course the chain reactions that would occur would be a run on food and chaos like we've never seen it. This isn't just a few whacos on the margins of society. There are major writers, economists, and web sites discussing the need to prepare. Your assault on people discussing this isn't resourceful, kind or necessary. Be curious instead of reactive.
Amigo, instead of being a newcomer looking for advice, you are rapidly turning into an agenda looking for a platform. You don't know me, or what I read, know, experience or believe. Therefore, it may be a tad bit premature to judge me, or anyone else, as incuriously reflexive.
My advice to you is to realize you were born with two ears, two eyes and one mouth. Use them in that proportion, and you'll do fine.
That said, it was a mistake to introduce a long-running issue with Yannadu/Pi2 on your thread. However, my advice would be to review some of his old postings (search under "personal nuclear power plant" and "solar ovens") to get a sense of exactly who you're defending. You'll find he has more in common with the Unabomber than with Updike.
Out of respect for the individuals you cited, I did a little fact checking. Not Wikipedia, but financial players. Turns out, none of the writers you cited are "major thinkers," except in the niche world of chicken little investing. Their advice usually is dependent on a pessimistic (as opposed to soberly realistic) world view.
Yeah, I know, they said the same thing about Noah, right? Turns out his source was a bit more credible than Marty Weiss and the "sky-is-falling" crew.
As a business owner and active investor, I have happily and profitably placed long term bets to win. Yeah, I'm sure we're in for another adjustment or two, but that's the cool thing about the "long term, isn't it." The world is evolving, but not coming to an end. No matter how much Larry Edelson wants you to think otherwise.
Meantime, enjoy hoarding gold and water purification tablets.
