Attempting to value individualism over collectivism is similar to trying to establish which came first, the chicken or the egg.

Having experienced both – collectivism and individualism put in practice as political principles, I have noticed that neither extreme is capable of working in a sustainable manner.

Communist regimes had fallen one after another.
Fascist regimes did the very same thing.
Pirate republics could never resist for long.

Coming back to what is happening in the US, I’m afraid very few people are aware of how much collective thinking had been embedded in the American Psyche. The good kind of collective thinking…
Americans go to church. A place where you go to to be together, not alone.
Americans used to help each-other. Charity used to be a big thing. Slowly, it had become a dirty word.
And so on.

Individuals can not exist on their own. They need each other to survive. And to thrive.
Collectives can not last for long unless the individuals who constitute them do respect each-other. Help each-other maintain and develop their individuality.

As simple as that.
