taxes

[Kelley Walker]

why is it that no one ever makes the argument that there is no need for 
taxes under marxism, at least not at current rates? on the model of 
anarcho-marxism, local control, and workplace democracy (say an improved 
parecon model) i can't see any reason why we need more than the barest 
bones of a national state and just the slightest amount of tweaking supply 
and demand to make sure that there were people doing the "dirty" work.

so, i guess i'm asking, explain why we need taxes under capitalism? (taxes 
at any significant level), particularly given the premises marx seemed to 
be working with re human nature, the character of non-alienated labor, etc.
