I understand that 51% of Wikipedians on the page for "Socialism" have come to this conclusion, but it may trouble you to know that 51% of Wikipedians on other pages about other aspects/flavors of socialism do not agree, let alone political scientists as a whole.

I'm sorry to be so snarky about this, but "socialism means command economy" is the Scholar's Checkmate of Internet political science debates, and I'm think we benefit by not dignifying it.
