The usual couple off the top of my head are:
-communism killed 100/x million people.
-communism will inevitably become corrupt when a single or several dictators/bureaucrats take over power.
I have been listening to a communist podcast (the spectre of communism) which easily refutes these but I am also putting it to a wider audience for comment as of course their opinion is going to be biased however I am very convinced by their arguments.
To the first one they say that yes communism killed however many but capitalism has killed far more spanning the course of history and capitalism is killing more day by day by hoarding wealth and is not the utopian system that pro capitalists make it out to be.
Another argument is that people like Stalin bastardised communism where it was no longer communism and so communism should not have to answer for the crimes of individuals. They stated that Lenin, who espoused the true school of communism, was against Stalin and tried to get him out of power before his death.
To the second point, the capitalists love to shoot this one out - that human nature is greedy and if you give anyone power then they will inevitably become corrupt. Again in the podcast they show examples that human nature is far more in line with communism than capitalism; the latter having developed only recently since fuedalism and private ownership. They give examples how before this in our past history ownership was communal among the tribe and also more recent examples of the native americans with example stories from the europeans (so not biased towards communism) who wrote about how the natives were basically living a communist way of life and extended that to the white strangers too until of course the natives got bitten badly by that.
Also it seems the idea of one or a few people in power hoarding all the power is a fallacy, from what they said. I am still learning about it but what they are saying is that under true communism (not stalin or such) then every field will have an elected bureaucrat but they will not earn any more than the workers they represent and they can be voted out at any time. So they say under true communism this single dictator phenomenon should not happen.
I had previously written I veered towards anarchism because of my concerns about this centralisation of power under communism. In their explanation though it sounds very similar to what had been explained to me in my previous thread on communism vs. anarchism, of how anarchism is organised. So if that is the case, that in fact real communism should not centralise power among the few then I see no cause to look further than communism.
They also explained that since the proletariat would be the ruling class, and since they are the majority in society, that would protect against power of the few, due to the above, that the few who are elected are not given higher wages or special privileges and can be voted out by the ruling proletariat if they arenât doing a good job of representing the latterâs interests.
I donât know enough about communism to say one way or the other on those points but very interesting and seems that what is usually bandied around the internet as communism is just a capitalistâs tarring of it and not real communism.
