It may indeed mean - giving up a prevailing notion of ~ I/Me against the world, and in a zero-sum game: desiring to 'own' as much as there is, no matter if it comes from You or Many or even: All the Rest..
Even in USSR (as moffitt would be the more competent judge) - the usual ego strokes went to superior performers, whether Aces in the military or doctors able to extract a pineal gland through the nose. After all, superior personal performance *indeed* adds to the society's performance. But at about that point.. the conditioning of which you speak - entered into a quite uncommunal distribution of Good goods, apparatchiks and all the rest now common knowledge. That-all was *nothing to do* with communism; a REAL Red-Herring, that!
Trying to write a New Rx to replace the above focus of infantile-ego which you deem 'natural' - ever fails, for reasons mentioned before: we aren't even grown-up enough to understand "'sharing' of a toy" let alone a planet. It is a Western religious (and religion-inspired) notion that you present as virtually genetic and immutable. I demur.
Small experiments all along, demonstrate to my satisfaction that - it is merely a mindset of long habit, reinforced precisely as Mike's little nursery story eloquently illustrates to a T.

PS and related: no wonder! 'Christianity' is ever given lip-service by the multitudes, yet practised only by infinitesimal numbers (and quietly) who might have understood.. what it was that Jesus was preaching. Marx said starkly the function of That kind of 'religion'... Result:
The truth shall make you free..
But first.. it will piss you off.
