The shoe fits on the other foot as well. Both extreme communism and extreme capitalism have tendencies to turn into dystopian nightmares.
If ‘1984’ alarms you; so too should current works like ‘Ready, Player One’ or ‘Ender’s Game’ and it’s associated sequels.
Extremism in general tends to not work. I don’t pretend to know what the exact right balance is; but it does exist.
