I gradually realize that many family conflicts are never about lack of money or housing, nor about living in poverty, but about everyone being trapped in their own small world, with no one truly "socialized."

The so-called socialization is not about being slick and hypocritical, flattering and fawning, but about understanding human feelings, knowing boundaries, understanding rules, and being able to empathize.
Knowing how to handle affairs externally with dignity, and being tolerant and responsible internally, can handle life's trivialities and also resolve family internal conflicts.
If no one in a family is perceptive or clear-headed, everyone will only engage in mutual internal struggles and blame each other, and life will become more and more tangled.
The biggest fear in a family is not poverty, but everyone being narrow-minded and stubborn, with no one understanding tolerance or having a broad perspective.
