If "...the developing world's share of global GDP has climbed from 37% in 2000 to 50% in 2012", then a hiccup within these economies can easily give the developed world the flu;
If "...developed economy exports to developing economies ...climbed from 20% in 2000 to 35% in 2012", then we are relatively very dependent on selling stuff we make to them as well;
This isn't new information, but information that if enough people figure out and react to before others do, may mean the difference between relatively high standards of living for some who understand what is actually happening going forward, and relatively low standards of living for many who don't know, and won't know until the affects have already taken place.
"Greater Fool Theory
The greater fool theory states that the price of an object is determined not by its intrinsic value, but rather by the often irrational beliefs and expectations of market participants. A price can be justified by a rational buyer under the belief that another party is willing to pay an even higher price. Or one may rationally have the expectation that the item can be resold to a "greater fool" later.
In real estate the greater fool theory can drive investment under the expectation that prices will rise, or force need-based-buyers to out bid irrational or ill-informed buyers. ...This phenomenon may also occur among banks offering real estate financing.
...the greater fool theory (also called survivor investing) is the belief held by someone who makes a questionable investment, with the assumption that they will be able to sell it later to "a greater fool"; in other words, buying something not because you believe that it is worth the price, but rather because you believe that you will be able to sell it to someone else at an even higher price.
Art is another commodity in which speculation and privileged access drive prices, not intrinsic value..."
With stuff like this, the greater fools usually end up holding the bag are the majority of populations that didn't pay attention, or were coerced into staying the course set by those who stand to profit from not changing directions, in my view.
Artificial stability breeds ever greater levels of real instability.
I believe there has never in the economic history of this planet, been this much artificially created stability imposed at any where near the scale of the present moment.
A period of consequence, I fear we are entering.
