The latest belief is that Sovietism was a Potemkin Village from the start and that the West's belief in the illusion until the "surprise" in 1991, helped to prop it up.
But Sovietism never asserted that nobody needed to work. The basic error was that people would work hard for the glory of it rather than for reward. Like so many easy answers, this one was plain wrong. The absurdity of paying policemen and soldiers less than the cost of living and even then being months in arrears shows the daftness of it all.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
