I genuinely think the main ideological function isn’t even as much to promote that, as it is to focus personal dreams and fantasies towards wanting to become a part of the “winners”. Not that it isn’t part of it, just by normalising it as status quo even within fantasies, but I think even more powerful is to have people fantasise about being one of the chosen ones eventually.
Quick reminder that stuff like this is not planned like in some conspiracy, but just a result of dynamics happening (almost exclusively, rare exceptions) unconsciously the way ideology springs from the material base.
