Well, I have to consider the source, TBH. Paul Ferrell, IMO, has been long on fear-mongering and very short on any factual predictions. I don't think we're in for some horrible Great Depression worse than any we've seen before. I think that we're in for a rough ride and any of the factors he listed can be contributing to the problem. Some, we have very little control over. For example, if some rogue nation attempts an attack on us, it could hurt us and our economy... but I bet you, like after 9/11 it would unite this country again and make it stronger. I also don't think that many of these factors are likely to come together to create a "perfect storm". Could they? Sure... anything's possible when you're predicting the end of the world. We could have an interstellar gamma ray burst that strips the Earth of its atmosphere and all die today.
I tend to follow, Paul Krugman, the NYTimes Nobel Laureate of Economics at Princeton, who is more moderate and, IMO, smarter. I believe that he states level-headed facts, follows them up with solid economics, and gives an opinion (albeit a bit an opinion a bit left-of-center) that neither incites panic nor gives people an excuse to put their heads in the sand. He thinks we're in for a rough ride, but it's not the end of the world. I think we could see what could be called a worse recession/mild depression over the next few years, still. I also think it can be headed off, as Krugman says, believe it or not, by propping up unemployment... get the people working again even if it adds to the deficit. Debt isn't necessarily bad. Sometimes you have to use it to your advantage. That's JMO and of course not everyone is going to agree with me, but there it is.
I'm not changing the way we do any of our investing or anything else. I already prepare for economic downturns, blips, upticks, etc. I'm an ant, not a grasshopper, so while I'm worried, I'm aware and prepared, and that's the most important factor.
