"Actually there's a pretty good book entitled" This Time Is Different"
That's classic they have a book now & it doesn't suprise me at all - not that i know anything about the book. But i do know throughout history those words have been used time & time again, through many market cycles - largely though it's always been more a case of delivering what people "want" to see/hear in anything where their money & dreams are on the line.
I guess all it comes down to though is the title
"This Time Is Different"
But the outcome can only ever be viewed in hindsight...
