This is true, though the one difference is that this form, rather than make communism/cultural Marxism happen, may have been done to KEEP those things from taking hold.

For communism to actually succeed, it has to be something where everyone is on the same page. In communism, if one person- literally only one person in the whole wide world- decides to act in their own best interests and get greedy, then the whole thing falls apart. Either you have to give them what they want for the greater good (and have everyone else say "why does THAT asshole get his way? I want as much as he got- hell, I deserve MORE than what he got because he was a dick and I played by the rules!" and you guarantee you'll run out of enough to go around), or you kill the greedy person and become a totalitarian government who has an excuse to kill anyone they dislike.

Communism needs everyone to play ball...and secretly, since most people are genuinely good and see the issue, the majority of the world would be willing to play ball on paper.

The people who have power now hate that. And they know that if the people who don't have power overtook them, they wouldn't have a chance.

Cultural Marxism, as such, is less about making communism happen and more about dividing the world into groups so that they can conquer them- each time saying to the groups "no, no, we're on your side. If it was up to us, you'd have this power- but THEY won't let us. They aren't as poor as you- they're richer than us and they pretend to be poor because they get off watching your pain. Why, if they were out of the picture, we could give you what you want!", and then divide those groups up, and divide those, until you have everyone in the world at everyone else's throats.

Never forget, the people in charge want the world to be poor, stupid, and bigots. They want you poor enough to do whatever they say just to survive, they want you stupid enough to believe their lies, and they want you bigoted enough you'd be happier seeing the group you're bigoted against suffer a little bit more than you do than you would by getting what you need to live.
