"Theres nowt wrong with communism as a concept. Its just that human nature means it could never be implemented in its truest sense. It just couldn't work."
Depends what you mean by 'work'. Capitalism 'works' very well for a small proportion of the world, but it depends on the poverty and misery of the majority to do so. How many men women and children died of starvation and preventable disease today while a handful of people sit on unimaginable wealth?
I'm sure that the slaveowners told the slaves "feudalism is a nice idea but it doesn't work".
Then the kings and barons told the middle classes, capitalism is a nice idea, but it doesn't work".
The driving force behind capitalism is not the betterment of mankind, but the concentration of wealth in fewer and fewer hands. In the long term that is not sustainable - who will buy the capitalist's products if nobody else has any wealth?
