The whole economy reminds me more and more of the decline of the Roman Empire. Their biggest problem was that there were no consumers left to keep money in circulation and the economy afloat. You either owned lots of land and slaves that provided pretty much everything you need or you were a slave, meaning the only one you could trade with were merchants from outside the empire but as the empire expanded, those became harder to reach. War expenses spiraled out of control while the economy declined until it ceased to exist.

Now mega corps only trade with each other and threaten to replace all workers with AI and robots. Meanwhile the economy becomes stale, people buy less while politicians around the globe cut down the social sector, meaning people will have even less money to spare. Money won‘t circulate as much, slowing things down even further.

There are ways out of this spiral of decline but billionaires won‘t give up so easily. You can say many things about them but they are persistent as hell.
