I predict that we are due another financial fiasco.

I can't be wrong on that.

But I can't tell you when precisely, otherwise I wouldn't tell you, I would bet on it.

But we have about a 5 year window. My reasoning:

There are dips every 15 years or so. World wars (eg) etc can alter the timing, but it is about one generation. The last one was arguably 17 years gap. Because that is the generation (by and large) that didn't understand the privation and causes. AND anyway know better than their parents (who know nuttin'!)
But the internet and pace if innovation is quickening. And there is Trump, and there is Brexit and Syria and, poverty gap and, and ........... Game changers, and change cost money.

All in all I am being wise before the event this time round, even though I knew something was up in 2007 when I heard of 120% mortgages and housing being 5 times a man's salary.

Prove me wrong on the causes, but time will tell, on time.
