Capitalism. The longer Capitalism exists, the more it has to find new ways to stop/slow its own built-in death clock. If it doesn’t, it dies, due to problems like the Tendency for the Rate of Profit to Fall and rising disparity. Enshittification, so to speak.
With each economic disaster, the wealthiest of the bourgeoisie can claim large swaths of cheaper Capital at a discount, compounding the issue into a form of neo-feudalism that will eventually collapse under its own weight.
