@Ogion, that is arguably true, however there are many groups with vested interest in that not happening.
All the major trading partners have economic which will slow down if the US collapses. Any industry which sells to the US will suffer, there is no-one to make up that consumption (despite the increase in consumption in south and east asia).
That means economic instability all across the developed world. Massive joblessness, cuts to social welfare and healthcare. Violence is inevitavle.
@Ripple, as much of a fan of the technological singularity as i am, i can't help but disagree. We have an example of systems growing interconnected in greater complexity. The amount of interconnection and complexity is the only difference now. And yet a spiral of disaster collapse the bronze age 'civilisations'. The smallest lesson this teaches is that interconnected trading systems become interdependent. 200 years ago a massive war in europe, producing crippling debt and millions dead, barely registered in the independent US - it triggered a wave of revolution in the Spainish Empire of South and Central America, because the Spainish monarchy was kicked from power in Spain by the French; and most of the rest of the world saw some disharmony. We can look at the progress which has heen made since then.
Complex social rules control what is acceptable behaviour, when previously violence was used exclusively, complex financial instruments are used to predict markets, when previously we used gold to back all trades. Complex tax evasion methods mean ownership of companies is split over continents and profits are shifted to zero-tax/low tax havens, when previously profit was from and in a single state.
These complexities add new parts, always extra layers, always more to break should things go badly.
And the interconnectedness? It undermines local independence. It kills local economic behaviour, and break down community support structures. You don't need to ask your neighbour for a lift when you can order and uber online. It isn't economicaly to grow food for your family when you can grow and export coffee, and then import food from somewere else in the world.
All of these great things depend on ever more expensive and more difficult to maintain layers of complexity. Maybe the automation of thinking will give us another ten years of increasing complexity, and maybe we will see another few decades of economic growth. But as more and more conplexity is layered on, there is just more to break. (Whether that is logistical organisation, or corporate organisation, or state/inter state organisation... Look at the EU, that mess of inter-state relationships, on the verge of collapsing with Brexit...).
Look at some complexity theory. You will see the self-similar patterns emerge. We may learn from the next collapse, but i don't think we've learned much from the last one yet.
