The assumptions you make say a lot about you and very little about the capitalist system
a) The ultimate in capitalist development is a Porsche? (well millions live and dies in poverty)
I responded exactly to the examples given - Porsche & porage, how do you define "ultimate" - super rice? iPod? teflon?
b) The Soviet Union was/is the only alternative on offer to this system
What aternative model would you suggest - subsistence level barter?
How's that going to ease global poverty?
Unless a magic ray beams out of space and infuses every human with collaborative desire simultaneously, then even if the UK decided to adopt a huggy-touchy-feely-nobody-gets-a-wage economic model, then anyone who actually wanted to get paid would simply off-bugger to any other country they they felt like.
I suppose you would argue that the capitalist system creates the 'big thinkers' - shame you don't seem to be one of them. I suppose it makes you feel more secure that you can add the usual 'well, most folk are thick as pigshit in any case' (as though it is some form of inate human behaviour that would tend to legitimise your own cynical, selfish world view)
The Capitalist system generates the environment that allows consumer demand to be met, whether that's a gym shoe with a different logo, a smaller lighter MP3 device with better battery life or cheap rice.
"your own cynical, selfish world view" - see reference to magic ray above......
Nobody buys a Lottery ticket because they want to contribute to the common good - that's basic human nature.
