There's an oft-repeated factoid that recognizable organized civilizations last about 10 generations or 250 years on average. And then there's Strauss–Howe generational theory. There's no magic formula or universal fate except it's risky to have lots of corrupt, stupid leaders, injustice, inequality, and/or bad circumstances that do everything to avoid rare, effective leadership with integrity and labor wealth growing faster than capital wealth. Late stage capitalism is omnicidal and suicidal because the greedy fools involved tend not to care about or plan for the future, including a cognitive dissonance to deny anticipation of domination by externalities like changes in youth public sentiment, demographic shifts, geopolitical balances, and climate change. The current richest people in the world are drug addicts, warlords, pedophiles, and those who erroneously believe public beaches belong to them personally.
