Taking X% of an individual's outcome and putting it into a pool for the collective good sure sounds pretty close to: "Collective ownership of the means to production". Doubly-so if that X is more than 50, as that means you are working more for others or the collective than you are for yourself.

Any who, I really think the definition of "Socialism" and "Socialist" require an overhaul in our current societal climate. I'd say that back when that ideology was conceived, people saw people in general and themselves as barely more than "resource" cogs, and that the rulers or state had some sort of "effectively-divine" right to rule them. I would argue that civilized and connected society has moved past that, to the point that anything remotely close to actual socialism or communism would be equivalent to totalitarianism in people's minds. It would be seen as barbaric, and contrary to people's right to exist.
