This is a story as old, and probably older, than civilization and isn’t unique to elites.
It is the question of group interest versus individual interest; or national interest versus internal group interest.
National advantages have to be sustained. If you have a technological lead, you don’t give that lead to another nation which is a competitor. If you have a production lead, you don’t help a competitor improve its production anywhere near close to yours. You may give them something from the prior tech generation, maybe, but never the current one.
This is unfortunate, a better world could be created with more sharing, but that would require a world in which nations and elites don’t compete with each other in devastating ways.
