That's the core of every problem that's occurred to every massive human social structure we've ever created in history.

We create systems, the systems become powerful, a small group of autocratic people naturally gravitate towards wanting to lead, the system is taken over by this small group, the system is corrupted, the system fails, the system ends .... then we start over again.

It keeps happening over and over again and the common denominator is human greed (either in the need to gain money and wealth ... or in the need to just want to gain power over everyone)

The only systems that last are the ones where everyone has an equal stake and a shared power structure. But it's a balancing game that constantly has to be monitored ... because once we stop being vigilant, some greedy idiots will naturally start taking over.
