I think they do care. If someone like Mamdani becomes U.S president in 10 years - when significant segments of the population are unemployed and/or radicalized, the U.S can actually become real socialist - like REAL socialist. That means business owners lose parts or all of their business. What if Musk and Zuckerberg won't like it and fight? They're not really gonna have an army of robots, nothing large enough to take over a country. The state controls the monopoly over violence. The state controls the ability to print dollars to build a bigger army. Legislation will make it impossible for a private citizen to accumulate a private army. Guardrails will be put in place. Governments are not that stupid. I think the super rich have an incentive to see the current system keep ticking and not turn into a shit show, they will have no way to control what happens if it turns into a shit show.
