Whoa! has this thread gone off topic! I checked in here to see what effect the problems on Mars had on the discussion, but I can see we are mired in radical politics. Just to show I can go off topic with the best of them here is my two cents on some of the recent comments.
Nazism and Fascism both used the jargon of socialism in some of its propaganda, but neither had anything to do with Socialism. mactastic is right with his comment about corporatism. Just check out what happened to German and Italian corporations during their rule and you will find what Hitler's and Mussolini's agenda was all about. It is worth remembering the "official" name of the Axis powers was the "Anti-Comintern Alliance." Both parties (and others of like mind such as the Franco's Phalangists) were brutal responses to Socialism and attempts to stop the growth of the Socialist and Communist Parties influences.
The main difference in the terms "Communists" and "Marxists" is that Communists has come to mean (since the split in the socialist movements after the Russian Revolution) those who embrace not only the ideas of Marx and Engels, but also Lenin. Many in the Labour Party of Britain, German Social-Democrats, French Socialists, Israeli Laborites, etc. would call themselves both socialists and Marxists, but never Communists or Marxist-Leninists.
As to the idea that the redistribution of the wealth through taxes is some kind of version of Socialism or Communism - well, it is just silly. The ideas of Socialism start with the redistribution of economic power, not a few dollars here or there. It is about who controls the enterprise that people work in, not just how much taxes people pay or what social programs those taxes support. This is Socialism 101 stuff. If you're interested, read Marx and Engels, not Ayn Rand and the Libertarian Party distortions.
edit: you're for your -- hate that mistake!
