Another problematic feature of human nature that both of you communists and anarchists ignore is people being too lazy to work. What do your communist, Marxist, anarchist, "left communists" or "Hoxhaists" like what do those even mean to people who don't have an obsession with obscure "theoritical errors" in failed projects that are the errors themselves, whatever you want to call them, ist-theorists even do when they are confronted with that fact? Hope that us non-communist people would forget about their flawed-from-the-ground plans that would only result in disaster? Even past the "transition" or "socialism stage", what would keep ALL people "happily working for the betterment of mankind" as I have heard from communists so many times? The people in many Marxist countries couldn't do it even with force and torture and terror in many cases! And even if some of you respond like "We don't force labor people" then WHAT is stopping a majority of people to not work at all? How is it any encouraging that lazy people benefit from the non lazy people's labor?
First off, people aren't only motivated by money. It is an artificial concept created by modern society. If we were only motivated by money, then cavemen would have never been able to survive. Humans are mainly motivated to work by two concepts: The need to survive, and the desire to live. In a fully developed communist society, and even in the phase with the dictatorship of the proletariat, wage labour would be replaced with free work. For more on that, read Paul Lafargue's "The Right to be Lazy".
Secondly, countries like North Korea, the USSR, China and other places aren't Marxist, but rather, state capitalist. They've botched historical materialism and replaced with some damned "Great Men of History" theory, business's are still organized like a capitalist one (and let's not forget how these countries use stock markets and trade with capitalist nations, like the Lend-Lease deal during WW2), and a new minority replaced the capitalist class. The only Marxist country was the Paris Commune, and that wasn't even run by Marxists.
And finally, what is with your obsession with lazy people? If a man or woman doesn't want to work, then so-fucking be it! You sound like Bill O 'Reilly for Christ's sake!
"Whatever you do, never lose your fondness of walking. I walk myself into my daily well-being, and I walk out of all illness. I have walked myself into my best thoughts, and I know of no thought so heavy that one cannot outwalk it." -Soren Kierkegaard.
"Beloved imagination, what I most like in you is your unsparing quality. There remains madness, 'the madness that one locks up', as it has aptly been described. That madness or another..." -Andre Breton.
