The implication that they would all be killed or completely stripped of assets is the problem you’re trying to solve, however, that doesn’t have to be the action taken. Perhaps instead, the 8 billion people of the world decide to enact a society that insists that such accumulation of wealth is obscene and should be curtailed. Perhaps systems could be introduced to make the wealthy more accurately contribute to the society they profit off.

Billionaires become billionaires through exploitation. Exploitation of workers, financial systems, and political power for personal gain. Make them pay for all these things.

Pay for education of the people they use to build their companies. Pay for the healthcare of the entire population, which they degrade with their business practices. Pay for the infrastructure that enables them to do business. The roads, the safety nets, the national parks, the air quality, the water supply, the land they use. Make them pay to replace and repair, fully, any damage their business causes. Polute the stream, pay to fix it. Dig the ground for ore, repair the ground so it can be used again. Make them replace what they take from society for little or no cost because their goods are only affordable because they do not reflect the true cost of production. Make their businesses pay for all these things, and the cost of production will rise to include the true cost of production. At the moment, the shortfall is paid for by we, the people, which enables them to become billionaires. Exploitation.

We don’t have to kill anyone, or strip anyone of all their assets in some revolutionary action. We just have to make them pay the true cost of their exploitation.

Tax the rich. Use those taxes to repay their exploitation. Increase the cost of doing business to include the cost of repairing the impact.

People can still become very wealthy. But society will also become much stronger through the use of the extra revenue to benefit all.

To make this happen will take a revolution, but it doesn’t need to include guillotines, it just needs people to become aware. Sadly, the politicians and media are also owned by the billionaires, making the final step of collective uprising extremely difficult. But humans have done it many times before in the face of adversity, perhaps it can happen again.

Nationalize the assets

I was just yesterday talking to someone about how AI drones, specifically exactly AI drones, will be a pivotal piece of technology in a way I think even beyond nukes in some sense. With a decent AI drone swarm, it's not hard to imagine a SINGLE person dominating an entire population. The dictator's purest dream - none of those pesky military generals getting uppity.

I don't know if I like assuming that obedience is a genetically heritable trait. I've heard racists use this assumption to argue that racially Chinese people are more likely to be sneaky servile backstabbers because that's what their genetics are selected for due to their political past.

Controversial statement incoming: I also don't want to preemptively rule out the possibility of obedience, or anything else, being genetically heritable - even if it could lead to these uncomfortable conclusions. I think scientific studies should be done about such things to answer the questions of whether these personality traits are heritable, come what may of that knowledge. But to my relief, from the studies I've seen, personality traits heritability is on very shaky ground in most cases.

Matthew effect.

For anyone wondering, the effect describes the uncanny ability for rich people to put on red outfits and act like blind devils whilst bending the law in their favor as they bask in their own self-proclaimed peity
