The Soviet Union published GDP numbers. Services were not included. Go find a copy of Das Kapital (the commies have it all over the internet). Marx's obsession for manual labor and tangible goods is obvious. BTW, I never said that communism was a market economy. I have no idea where you got that.
Numbers that are meaningless when all prices are rigidly fixed and predetermined by central politburo edict.
Heck, in a command economy, central planners can make GDP come out to whatever they want. So what? It's all bogus and doesn't mean diddly-squat.
