A majority of adults are really just out of control children in grown up bodies
It makes sense when you see the state of the world and how much cruelty and chaos runs rampant on planet earth. So many people are emotionally unintelligent and suffer from arrested development. I believe if we valued emotional intelligence more over mathematical intelligence in school, it honestly wouldn't be as big of an issue. That is my opinion.
Edit: Maybe not a majority, but a big amount.
