My take on the "individualism vs collectivism" debate is that there's no such a thing as an individualistic mode of production and there is no such a thing as a collective mind
Our bodies are unable to survive alone, our species has evolved to focus entirely on language and dexterity. We can't hunt and sustain ourselves while defending ourselves while taking care of our stupidly weak offspring. We're materialistically extremely dependent on one another, there's no such a thing as an individualistic system of production. Capitalism is and extremely large collective structure, thousands of people worked to make everything that you have around you
On the other hand no one can read the thoughts of someone else. Everyone has a unique experience of life therefore everyone has different thoughts. Liberals would say that collective structures make us lose our individuality, but look at the effects of loneliness (extreme case being solitary confinement) and compare to how much "mob mentality" is making us different from just our regular life. Looks like it's isolation that destroys individuality. Looks like even mob craze is pretty harmless compared to its opposite
So basically, the economy is already a super collective, it's just designed by the people who arrived first at the nicest spot. And the mind is already unique so everyone will always remain an individual even within a super collective structure.
