Well, wait till we try to square what Americans commonly mean by 'liberalism' and 'conservatism' with continental political theory and classic theorists connected to these words. In these cases America is, interestingly, removed to the left. The man who "hijacked" the word socialism would probably be Marx himself, as he declared his theory to be the (scientific) socialism, as opposed to various (he said) "utopian" and "naive" thinkers who hadn't subscribed to views like historical inevitability of communism, or dictatorship of the proletariat. Then in the Eastern Bloc the local political systems were called "real socialism", i.e. the one put into actual functioning, on the road to future communism. So association of socialism with command economy is well established and not really one-sided ideologically, I think. The terms to use if you want to distance yourself from that heritage would be 'social democracy' (if you mean the ideas that were partly implemented in capitalist Europe) or 'worker democracy', if you want something more akin to what the GP described. These ideas are easy to sympathize with on many levels, and what passes for "socialism" in the US is often just the not-really-disputed social contract on the other side of the pond. Ultimately these ideologies advocate for reducing economics, to varying extents, to just democratic politics. Which is kind of boring: not necessarily meaning this as a bad thing. The calculation problem and related issues of organizing true command economy are more interesting as an abstract problems of engineering, organization etc., regardless of actually wanting this politically to happen. (Being formed in part by the Eastern experience, I am very much wary myself.)
