Life is a pyramid scheme. Rather than figure out a way to exist in a steady-state forever, our cells divide exponentially, accumulate genetic mutations until they can't take it anymore, and then rather than fix themselves, we just make new humans and let the old one die. Humanity in developed countries at least has the kindness not to make more humans than we believe have a reasonable chance of survival, but that restraint is not universal either within humanity or within the animal kingdom. Most animals just spray & pray and whatever happens to survive carries on the mantle of the next generation.
The universe is a pyramid scheme too - we know that thermodynamically, the ending state is the eventual heat death of the universe, but until it happens gravity creates this big positive feedback loop where smaller clouds of hydrogen coalesce with bigger ones, which eventually start fusing, which generates all the energy the universe will ever have.
We've grown to believe in steady-states and sustainable systems because until recently, the pyramids have not been birthed and died within the span of a human lifetime. Far enough down a pyramid's base and it looks like a steady-state, at least until it collapses. But now that we can watch economic systems get conceived, grow, IPO, and die all within a decade or two, we're waking up to the fact that pyramid schemes are far more ubiquitous than previously thought.
