My perspective has nothing to do with indoctrination, but is instead born out of historical knowledge. Communism has been tried again, and again, and again, and each time the outcome was the same. Capitalism has also been tried, and has lifted more people out of poverty than any other system we ever came up with.
The existence of the ultra-rich doesn't bother me. I wouldn't suddenly be richer if people like Musk or Bezos suddenly popped out of existence; their lives simply don't impact mine. If anything, their existence serves as an inspiration for others to try for big dreams. Many of those will fail, some will succeed marginally, and a very small number will join the ranks of the ultra-rich - because they managed to provide a service that millions of people were willing to give them money. What does communism have to offer, in comparison to that? Equal poverty doesn't sound all that attractive.
Now, if you were to argue that these mega-rich people and their companies have too much power, we would have something to talk about. I see the solution to that in legislation though, not in the complete destruction of our society followed by a century-long dark age.
