Don't comment on Marx if all you know is "lol communism didn't work in russia". That's a borderline non sequitur that just reveals you don't know what Marx said at all. It's like British people meeting Mormons and saying "Oh you're a real mormon? What like from South Park?" You don't have to read Marx in the original, just spend half an hour on a Wikipedia or cliffsnotes summary at least beforehand. Maybe do the same for Smith and Ricardo, too, so you can have a good overview.
It didn't work anywhere else, either, and it's been tried thousands of times. Note I did not say "Soviet Union".
Do you also refuse to learn basic physics because Isaac Newton was imperfect and despite coming up with some great physical laws, also believed some nonsense about alchemy that later was shown to be nonsense?
Do you bring up the craziness of alchemy every time newtonian mechanics comes up, and refuse to believe in momentum, mass, and kinetic energy?
Having to argue about this crap every time Marx comes up is tiring and intellectually ineffecient.
At this point I wish we could blame just the smart things Marx said on someone else like say, Mark Twain, just so the adults in the room can discuss the workings, benefits, and problems of capitalism without constantly getting interrupted by irrelevant low-effort arguing.
What I want is a good faith argument for something that works as a solution for Marx stated problem. What can we propose? What can we learn?
That doesn't have any relevance to a critique of capitalism. They both have problems. Also, even if we compare them on "environmentalism", that's only one criteria.
Pedantically, you are correct. But pragmatically, the people who write "capitalism is bad because of X" are usually interested in replacing it with leftism.
> only one criteria
Your post would be more interesting if you pointed out one criteria where Marxism is better.
These alleged people aren't here though. This is the definition of strawman arguing. Sorry, but you need to engage with the actual positions of the people who you are actually responding to, not the positions of some other people you once met somewhere else but that remind you of us. That kind of discussion is a total waste of time.
Marx is one of those people. His written words paraphrased here by you.
This sounds like looking for a fight that has been fought thousands of times before rather than looking to learn something interesting though.
To me a more interesting question would be, if we steel man the public conception of the problems of capitalism, and we accept that the public conception of communism is problematic to implement to say the least, what remains? How can we move forward without endlessly getting stuck in the same tired argument about communism? How can intelligent people discuss solutions to these issues? What are our alternatives?
