You know as well as I do that when Marx discussed "capitalists" he did not mean the rich. He meant what we now call the middle class. Managers. Engineers. Store owners. (Small) company owners. Factory owners. Smaller landlords. Perhaps upper middle class, but not the real rich, the families. He saw what everyone else in their time (correctly) saw: that larger land owners were mostly outside of cities, and were well on the way to inevitable bankruptcy. That the uber-rich are very different, and aren't rapidly bankrupting themselves is not something Marx foresaw.
Only the governments themselves, who are of course also very, very, rich would retain their wealth. And quite a few governments in his time were individuals or families, but he didn't see them as the enemy, kind of, but not as the "source" of the evil of capitalism. Of course, communists aren't against a very, very rich government. The Soviets initially offered to make Tsar Nicolas II the leader of international socialism. Only when he kept refusing did he become the enemy.
And then the "that wasn't true communism" argument! Thank you. I kind of agree: most other communists were MUCH worse than the Soviets, and especially lacked most of the redeeming qualities the Soviets retained from imperial Russia.
In fact, I miss that about the Soviets. The Soviets were going to conquer Europe, provide housing and jobs for everyone, and get everyone to work and back each day on rocket powered trams. Seriously. Today's socialists just seem to want to destroy everything, which will then encourage Gaia to save the world and care for everyone. The Soviets were very much going to exploit nature to make everyone rich.
Never mind that even the ancient Greeks knew better: the godess Gaia is a Titan who massacred, and then ate people. Men, women, children. Especially children. She was the embodiment of natural disasters, of the primal, absolute force of nature. She killed to save nature, true. But also just for fun, because it is her nature. Especially children. Especially lost children. She was like almost all Titans: considered completely amoral, not necessarily evil, but she needed to be fought, even destroyed, not for fun, because otherwise a LOT of people would die.
