What they want is global revolution that pushes the bar so far left that we go back to living in caves or in nomadic tribes, because they're following a Gnostic-adjacent philosophy that says we can only return to our true selves once we've stripped away everything that could people into an "oppressed" and "oppressor" class--ignoring the fact that even animals have the capacity to take "more than they need".
You're right. It's all part of the radical Communist plan to destabilize the nation and make it ripe for a revolt. A well functioning government and peaceful, satisfied nation is not fertile soil for a complete and violent restructuring.
You see, the thought leaders of the Communist movement realized back in the 50s and 60's that Western Culture and Capitalism made a civilization that was
too successful. Everybody was too comfortable with their lifestyles and cultures to accept the revolution and transition to a communist state. The answer to this dilemma was
not to reconsider if communism would really be that great in comparison, but instead to infiltrate and destroy all the liberal democracies and burn every institution to the ground. Once everything is garbage, then communism would look reasonable in comparison. Brilliant!
That is why they want to destroy all the systems that hold together and stabilize civilization. They want to undermine the voting systems and government, they want to subvert the justice system, they need to flood healthy cities and communities with criminals and racial strangers, they are uprooting and destroying shared culture, history and mythos. They have to turn everything into a literal trash fire as step one of their grand plan to squirm out from the wreckage of the West and smugly pitch Communism to whomever survives, because that is the only way their system will seem like a viable alternative.
Of course, it couldn't possibly work anyway because they've been running things into the ground for so long on purpose that they lost all genuine competency. You see, back then the Commie leadership was still a bunch of academics, same as today, but it had a backbone of actual factual laborers and workers. Blue-collar industrial types were in their ranks, so if the Commies actually seized a town they could run it in theory, keep the boilers going, trains and newspapers working, etc. For a while, anyhow, please see the USSR for examples of how long you can manage to keep a place limping under the Red Banner. (There isn't a Marxist alive today that could hold a candle to Stalin or the old Soviets.)
Not so anymore - the core is still a bunch of entitled academic rich kids, same as Marx, but now there isn't membership from blue collar or laboring factions. The entirety of the Commie Party is wall to wall untermensch, just useless scholars and students and 'activists' that are only good at Party dialectic, subversion, and riots. They can seize a railway, but they couldn't run it these days.
So if they do manage to somehow tear everything down and miraculously create the 'diverse Marxist utopia' on the carcass of a republic, it'll have a lifetime measured in months at best. They simply aren't capable of doing anything constructive, their entire philosophy is counter to reality and production.
