> Yet during the 1930s, when starving veterans were being shot dead in the streets of Washington DC, when unemployment in the US and Europe was over 20%, the Soviet economy was booming.
Oh yes. The US and Europe credited the Soviet Union well, and the Soviet Union paid in gold.
At the same time, Soviet authorities robbed its own people, partly by putting hundreds of thousands to forced labor camps, partly by just taking away their possessions. The great hunger of 1935, with massive human casualties, has happened because grain was expropriated from peasants to be sold for gold, and the gold was spent to build massive steel factories and weaponry plants, using American and German expertise.
With regard to shooting people dead, USSR was not shy of action at all. Massive death sentences in 1935-1939 witch hunt campaign plus cruel oppression of several riots against expropriations and hunger account for hundreds of thousands of deaths.

Trust me, this is not a model of growth you'd enjoy.
Regarding gamification — yes, that was one of brighter ideas. Too bad that real competition was often replaced by a fake that made bosses happy, using massive falsification of results.
You want a competition between producers? Have you tried the so-called 'market'?
