What If All the Cheap Stuff Goes Away?

What If All the Cheap Stuff Goes Away?

Nothing stays the same in dynamic systems, and it’s inevitable that the current glut of low costs / cheap stuff will give way to scarcities that cannot be filled at current low prices.

One of the books I just finished reading is The Fate of Rome: Climate, Disease, and the End of an Empire. The thesis of the book is fascinating to those of us interested in the rise and fall of empires: Rome expanded for many reasons, but one that is overlooked was the good fortune of an era of moderate weather from around 200 BC to 150 AD: rain was relatively plentiful/ regular and temperatures were relatively warm.

Then one of Earth’s numerous periods of cooling–a mini ice age–replaced the moderate weather, pressuring agricultural production.

Roman technology and security greatly expanded trade, opening routes to China, India and Africa that supplied much of Roman Europe with luxury goods. The Mediterranean acted as a cost-effective inland sea for transporting enormous quantities of grain, wine, etc. around the empire.

These trade routes acted as vectors for diseases from afar that swept through the Roman world, decimating the empire’s hundreds of densely populated cities whose residents had little resistance to the unfamiliar microbes.

Rome collapsed not just from civil strife and mismanagement, but from environmental and infectious disease pressures that did not exist in its heyday.

Colder, drier weather stresses the populace by reducing their food intake, which leaves them more vulnerable to infectious diseases. This dynamic was also present in the 15th century during another mini ice age, when the bubonic plague (Black Death) killed approximately 40% of Europe’s population.

Which brings us to the present: global weather has been conducive to record harvests of grains and other foodstuffs, and I wonder what will happen when this run of good fortune ends, something history tells us is inevitable. Despite the slow erosion of inflation, food is remarkably cheap in the developed world.

What happens should immoderate weather strike major grain-growing regions of the world?

Then there’s infectious diseases.  Global air travel and trade has expanded the spectrum of disease vectors to levels that give experts pause.  The potential for an infectious disease that can’t be mitigated to spread globally is another seriously under-appreciated threat to trade, tourism and cheap stuff in general.
