What I wrote is from Economic Problems of Socialism in the U.S.S.R., yes. Not your claim though, considering that Stalin wrote that work in 1952 and died a year later.
It's from "Economical problems of socialism in the USSR"
I haven't heard about that. Stalin did want to replace commodity-money relations in the countryside with products-exchange, a concept which was attacked within mere months after Stalin's death by the Soviet revisionists (just without naming Stalin personally.)
Somebody told me that after Stalins death in the "biggest"(sry I am translating from greek I can't fding the correct word for it) soviet there was a suggestion for the next five-year-plan for 6 hour 5 day work and the slow abolition of trade value(money).And that it was cancelled after the "destaliniasations).Is that true?
