It is contrary to human nature. It will only work by force. That is what is wrong with it.
I don’t think that argument will convince any leftist.
They believe that human nature is inherently good (THE basic wrong assumption),
and that with the right structure (ie, force) in place,
that inherently good human nature will flourish.
So, your argument is actually SUPPORTIVE of the left’s view of communism.
well, that's communism as a whole.
Bolshevism is the creation of a party of "elite" "elect" (but not elected) folks on top -- Bolshies are an oligarchy, which is according to human nature. The policies they tried to implement on the lower masses (communist policies) including utter control of supply and demand was communism and THAT is contrary to human nature.
Only in a monastery or a kibbutz or to some extent a university can free sharing of resources occur. It doesn't work outside this rarefied world and even the monasteries, kibbutzes and universities interact with the capitalist economy, but as a united group of individuals. Communism is a failure and hard socialism that is practised by the democrats of today is also going to be a failure...
In the current vernacular, I believe that's "YOU didn't grow that!"
Kinda spooky how life in America today echoes the Old Country that Grandpa escaped 100 years ago, ahead (thank God!) of the Povolzhye Famine & Holodomor that wiped out millions who stayed behind.
Established in the US, hearing what happened to family in the Workers Paradise, Grandpa got himself a gun, and I'm told he noted, "Someday the Bolsheviks will come knock on the door here, but I'll be ready." Yes, Grandpa understood exactly what the Second Amendment was about: no longer an unarmed peasant at the mercy of murderous apparatchiks.
As little as ten years ago, I would consider such remarks silly & extreme, a product of his life experience.
"Never in America!" I would think.
Today, I feel very foolish, and sad that we've allowed the country to slide this far down the commie rabbit hole.
