The differences in behavior in people from different generations are affected both by generational differences and by common experiences shared during their childhood, forming worldviews that are distinct from one another.
Our childhood experiences shape our worldview, and the way we react to stress may mimic what we learned as children. For instance, going on YouTube to express emotions may feel like vulnerability, but it's often easier than asking for help from a friend.
The speaker suggests that differences between older and younger people exist beyond generational differences and some younger people have not learned necessary life skills. The school admission scandal is cited as an example of harmful behavior that may not be helpful for the younger generation.
