You are right about Denninger.
Two things that I find particularly annoying. First, he goes out of his way to fault the Tea Party and Republicans. He fails to recognize that the Democrats, and a subset of the Republican party, are exclusively to blame for our current predicament. It wouldn’t fit into his “I am the only smart person in the universe” theme.
The second is that he fails to understand how moral decay forms the basis for our inability to solve these problems.
Having said that, however, he is quite right that we have gone off the cliff. But, as you say, there are many others out there who realize this.
Well, yes. And, for a long time too.
On the other hand, how does the number of those who have said such things compare with the number of those who (1) hear, and having heard (2) concur?
This is a lot of the reason why folks like Denniger become so strident. Can you imagine how Enoch sounded by the end of his near-millennium-long preaching career on the coming Flood? LOL
No one's known how long it'll take for these fiat currency schemes to implode. It sure looks like it'll be sooner rather than later. Perhaps Greece gives us a bit of sense for how to interpret the end-game for the rest of the Western fiat currency regimes. If so, then we don't have much time left -- a few years at the outside.
Meanwhile, "what to do?" has also been clear from the beginning:
1. Protect whatever wealth you do have by putting it mostly into some commodity or tangible resource, and,
2. Lay aside some form of provisions to tide you over the most extreme economic reprocussions of an economic crash.
My own sense is that the latter provision does not need to be for more than a few weeks at the outside. A totalitarian regime will quickly fill any vacuum an economic collapse creates (history shows this emphatically!), so it won't be long before the new strongmen (or, horrors, strongwomen!) will have the trains running on time again.
