You'll start seeing more stories like these.
I wonder to what extent Warren Buffett's treatment as a oracle by the financial press creates a non-helpful feedback loop where complex financial activities that can't be reduced to simple homilies (i.e., buy low, sell high) are immediately viewed as inevitably catastrophic and diabolical.
I say this with particular focus on the notion, which is once again stated in this article, that if Buffett doesn't understand it, who does? Apparently, a whole lot of very very smart people understand these systems (exotic financial instruments, electronic trading systems) enough to make them a significant part of the modern economic structure. Certainly, there is something more complex and nuanced going on here but you would not know it from the way the press (via Buffett) is presenting it.
Headlining this story 'Warren Buffet: *' is very misleading. Please don't.
