It's not like this is surprising, there have been plenty of sci-fi books/movies that have predicted this very thing. How many movies have the haves lived above ground/off planet, while the have nots have lived underground or stuck on a apocalyptic planet.
This is just furthering the previous history. Currently, the lords have just been able to keep the serfs appeased to a longer extent. Every time in history or in sci-fi, the serfs reach a breaking point and rise up.
You seem very confident. This seems to imply you feel the haves will know when to leave enough on the table for the have nots to still feel like they are a part of the haves. I'm not so confident in that.
People in technologically advanced societies have more than enough & the people who are not as advanced can not do anything that will have any effect on the people who own the fighter jets, missiles, robot factories, & "internet" satellites. The current system has no historical precedent. It is very close to an almost perfect panopticon w/ an associated media & police apparatus to keep everyone docile & complacent. Like I said, this time is different.
Far more likely is that we head back to a feudal era where data mining tech is used to identify and eliminate potential rabble-rousers. Once enough production is automated, all remaining have-nots are exterminated.
The weak link is that for “the haves” to have, the “have -nots” are needed. To have or to not is just a comparison, a millionaire needs the poor to be rich and to feel special otherwise when everyone is special nobody is.
It will instead eventually fall apart in more thoroughly destructive ways. But not until it does a possibly-unrecoverably (at least in the medium term) amount of damage to civilization, humanity, and life on Earth first.
