A QUEDA DO IMPERIO :

"Vai a 2031, depressão estrutural. Acumula 3 megacrises, décadas: dívidas, dólar, euro". 

This depression is structural. Our current depression likewise has its roots in three huge crises coming together at the same time. We have a debt bubble that had been building up over three decade and which burst spectacularly in 2008. The dollar is in long-term decline as a reserve currency, and as the anchor for the global monetary system, but there is still not much sign of what will replace it. And in the euro, the biggest single economic bloc has created the most dysfunctional monetary system in human history, threatening financial collapses on an unprecedented scale. Think of it as the world economy’s suffering a heart attack, then a stroke, then getting picked up by an ambulance that crashes on the way to the hospital — it is hardly surprising the patient isn’t in good shape.
