As I mentioned, the examples of this working out in real life. Not so good.
The USSR, currently dissolved and not a model I'd be interested in emulating.
The folks I know who lived in it don't want it back either.
This is nothing but anecdotal evidence and a blanket claim that the USSR was bad just because it was illegally dissolved. Although it varies from State to State, the majority of residents polled in former-Soviet countries approved of the USSR and wished for it to remain.
Cuba, I'd say they had equality for citizens which they don't, not a good example either.
Genuinely, what do you mean by this? They have far better quality of life metrics like life expectancy, and more democratic means to sway things than they did under Batista and fascist slavery. It has a more progressive LGBT legal code than America does these days.
China... Really?? Marxism? Really??
We're glossing over Mao Zedong and a history of mass murder.
China is currently Dengist, ie practices Socialism with Chinese Characteristics. If you want to read about it, consider reading China has Billionaires. The PRC shifted away from Maoism, an evolution on Marxism-Leninism, after the Cultural Revolution. Despite the myriad failures of the Cultural Revolution, Life Expectancy still doubled under Mao, and there was a nearly totally equal redistribution of land from the landowners to the peasants.
You're expressing wonderful ideals.
They don't seem to line up with the execution in the real world though.
My argument is that it won't and hasn't ever.
You haven't really made an argument yet, you've made blanket statements like "I don't think so" and whatnot. You haven't analyzed anything, and some of your points are directly disprovable with a quick google search, such as the bit on Cuba and the USSR.
When a developer writes a program that doesn't do what it's supposed to, it gets rewritten.
Marxists just keep trying the same philosophy. Maybe if we murder more people it'll work.
Again, false and vibes-based. Marxism has evolved over time, Marxist thinkers have introduced new analysis with existing theory. That's why there's even such a thing as Marxism-Leninism or Maoism.
Additionally, you make it seem like Marxism is when you murder people, which outside of Revolution is historically false again.
Do you have any real points, with supporting evidence, or are you content with just vibing your position?
