Sorry, are you referring to the dictatorial planned economies of the soviet union?

Ok, here's my impassionate take on Marxism (I know Marxism != socialism).

The fundamental tenet of socialism is the idea of dialectical materialism (https://en.wikipedia.org/wiki/Dialectical_materialism) which basically states that there are two forces engaged in an endless struggle and future state is a result of synthesis of these two.

There's a close relationship between say Engel's dialectics and something like linear logic. However, Engel's third "The law of the negation of the negation" is fundamentally flawed. You provably can't have both adversarial relationships and still allow double negation.

Socialism doesn't have to be more than a principle. In fact, every capitalistic system has it in some form. So I think your point is dully contrarian.

Socialism together with some capitalism is really the way to go. Having one of them totally uncontrolled to an extreme level is what leads to problems.
