Yes, that is true and those obscenely rich people shouldn’t exist.
But, for me, anything is better than being at the mercy of a tyrannical regime hell bent on controlling all aspect of your life, turning people against each other and removing them for their opinions.
The USSR era was the worst thing in the modern history of Europe (yet) and anyone who idealizes it is, at best, scum.
It is. Education would not be sufficient for that unless you can program people with chips in their heads.
You then get a few people who produce something that is desirable and rare, start exchanging it for favors and you’re on your way to a systemic collapse.
