Why did the great nations of Europe essentially commit suicide in 1914-18?
The answer, it seems to me, is the marked tendency of any society’s political class to be captured by interests and ideologies that have little to do with the interests of the people they govern. Apart from bankers and arms manufacturers, the Great War of 1914-18 served no one who lived in the warring countries. On the contrary, it sent millions of their young men—including their most educated young men—to be machine gunned and gassed in the trenches.
While some elements of the state are necessary for providing basic security, maintaining critical infrastructure, and adjudicating conflict, the state invariably becomes way too big and parasitic, and ultimately cancerous.
I fear that Britain, France, and Germany are currently suffering from Stage 4 Cancer that originated in the bosom of their bizarre governments run by total weirdos who in no way represent the interests of the people they govern.
