I find systemic thinking is one of the key differences between the liberal world model and the dialectical one. Communists recognize that the structure of the system creates pressures on society, and people act according to those pressures. Meanwhile, the whole system evolves based on collective actions. So you have this dialectical progression towards the future of a dynamic and ever changing system.

On the other hand, liberals reject systemic thinking and see the society as simply a group of individuals each acting in their own best interest completely independent of one another. In this model there is no overarching system in play, and everything becomes a discrete event. Things like wars and economic crashes just randomly happen because of some random event like the pandemic or terrorist attacks. There is never a question of how things evolved to a point of a crisis and how things could've been done differently.

The liberal world view is infantile and we're now seeing what an utter disaster this ideology has produced globally.
