I'm not sure if "crash" is the problem. Crashes happen in markets, it's part of the business cycle. OP is discussing a 30+ year time horizon, though. I can think of a few potential things that would precipitate not just a crash, but a long-term economic malaise: - Climate change - Political/social unrest (extrapolate Brexit, Trump, etc) - Mass unemployment caused by automation (you can't "retrain" 5MM 50yo truck driv…
> Empire collapse (has happened with every single empire in history - what makes the U.S. exempt?) The US isn't anything like traditional historical empires for one. It hasn't built its prosperity on invading other nations to annex them and plunder their national wealth, which is traditionally how empires temporarily sustain themselves. The US built its immense wealth today (just under half of all private wealth on e…
First, Bretton Woods established a system that heavily favored US interests -- it was based on dollars and gold, and the US had most of the gold supply. The US was able to achieve this favorable position thanks to its place as the major merchant-state, lender, and latecomer ally/victor in WWII. Among other effects, this system led to the dollar becoming accepted as the foundation for most international trade in the latter 20th century.
After the dollar's position became less favorable in the late 1960s, the US ended the Bretton Woods system and worked out agreements with OPEC to shift oil trades into dollars. This had the effect of cementing the USD as the currency of global trade (among other benefits), as all countries needed to hold dollars in order to purchase oil. This "agreement" was backed up by US military and economic hegemony.
Additionally, during this time, the global "south" was being pillaged for resources -- particularly oil, but also cropland (see bananas and sugar) and other scarce resources. The US established and propped up dictatorships that were favorable to its aims under the guise of fighting Communism. The USSR was doing the same thing in reverse, of course -- a grand game of chess, with the spoils to the victor.
Finally, the US "won" against the USSR through a combination of clever psychology, propaganda, and economic warfare, as well as Soviet mismanagement. When the USSR collapsed, the US obtained some economic benefits from the disentangling of the Soviet system, prolonging its advantage.
The US position was unsustainable, though, and this is when the shift occurred. With the relative increase in global stability and international "free" trade, as well as the power of the Internet, corporations no longer needed the protection of the US system quite so badly. Outsourcing and distributed operations became more and more common. The US position is not so rosy as it once was. The petrodollar system seems to be unwinding as well.
I do live in the US, so I do hope that the inevitable correction is a slow one. I also hope that we can avoid starting new conflicts in an attempt to prolong or reestablish our advantage.
