For a given value of "better"?!
"It may have been more efficient, and relied less on brute force and memory and more on elegance of construction, but that was about it."
So in other words, it WAS better, no qualifiers or evasion necessary.
Overall, it sounds like you were all very successfully taking advantage of your fellow man in the greatest spirit of capitalism. Well done you.
"the rubble that a socialist attempt at the world leads to" - Surely you mean the rubble that a totalitarian, pseudo-socialist cock-up of an attempt leads to, which is a far more accurate characterisation of the Soviet system.
And no, the basic Marxist logic wasn't wrong, it was the totalitarian state that was implementing it, creating a political climate where it was far safer to toe the party line and, as you say, "adhere to every ridiculous detail" rather than try to come up with logical, workable methods and systems. Socialism was an attempt to come up with a fair and compassionate system of resource allocation. It may have failed, but the fault was more Stalin's than Marx's. Capitalism, on the other hand, is by it's very nature heartless and unfair.
Rather than sing it's praises, maybe we should realise that we still haven't found any particularly good economic system, and maybe we should all work together to find something new that works for everyone rather than the lucky few?
