Communism starves our human impulses to succeed and grow
Nothing about communism forces human impulses to be ignored, unless you mean the impulses we already suppress as sentient beings, such as fucking everything that moves or eating until we literally die.
All of which can be achieved in a communist system, only instead of "look at my huge paycheck", it'd be "look at all these skills I've acquired thanks to free public education and more free time". People would stop mindlessly showing off innane manufactured waste and start actually acquire useful knowledge.
