Capitalism is driven, not by money, but by energy. The powerhouse of turbo capitalism was unleashed in the late 19th century, first by coal, then oil and finally natural gas. These fossil sources of encapsulated energy were vastly superior to anything else, and easily accessible and portable.
However this bounty is coming to an end, and the economies powered by it are creaking at the seams. Most of the West is threadbare and cannot manage to sustain its constant wars and support decent lives for its population. Most conventional economists and governing parties are driven by the cult belief that the economy is a financial one, not understanding that the economy is an energy system.
There are three emerging trends:
The first such trend is the growing inevitability of a new financial crisis, which will dwarf the 2008 global financial crisis, and engulf the whole of the system.
The second is the progressive incapacity of the existing political systems to rise to this challenge, a process resulting from the widening divergence between the delusions of the political class and economic reality.
The third is the clear danger that the current, gradual deterioration in global prosperity could accelerate into something far more damaging, disruptive and dangerous. The rise of far-right forces like Reform in the UK are a clear indication of this. MAGA and Trump in the USA likewise.
Renewable energy is too diverse, and actually dependent of fossil fuels for its production and implementation to actually replace fossil fuels in a major way.
Various heterodox analysts, such as Peter Turchin have put forward theories of stagnation and collapse based on wave formations of expansion and contraction over the years. Many civilisatonal collapses have had energy components, such as the Mayans, who suffered losses in croplands and thus food, or the Easter Islanders, who ran out of trees for fuel and in a couple of generations had to resort to cannibalism.
The instability of society is bound to cause a lot of problems, especially as no political party has any real answers. Blaming immigrants, as right-wingers do, is not a viable method of rising to this challenge.
