This thread was a really interesting read. Almost unbelievably, I'm actually going to agree with AltyTunnelSteward. People appear to have very strong views one way or t'other...
Politics is a very complex business, not only are there economic ideals of left/right, but also liberal ideals of liberty/authoriatarianism. Wherever 'communism' has been implemented it has been in an authoritarian way. Whilst Marxists would argue that means communism was corrupted, I wouuld make the point that the only way you could bring about communism is by authoritarianism, and therein lies its weakness.
Personally I favour a mixed economy along the lines of Scandinavia. Big investment in health and education (proper investment, not just raising teachers' salaries and hoping that'll help kids do well in their SATS), but with incentives still there for businesses and workers (i.e. more staggering in the income tax brackets, but with a top rate no higher than 50%).
As far as I'm concerned, and this is obviously completely biased, we're now in a situation where we're living 'Thatcher's Dream' and it's rubbish. Mass privatisation = Greater Competition = Higher Standards. What a load of bollocks that turned out to be. Public transport is worse, hospitals aren't clean because private companies can't be arsed to clean them properly, people don't get their medication delivered on time because that NHS duty has been contracted out etc etc.
