"lack the emotional development to know these things"
Being told things (at any age actually, think of having a conversation with your doctor about a medical problem) allows you to frame and put things in perspective. The perspective is what is important and what can be very helpful. So a more experienced person (who could be older or could have just gone through the hoops) tells you "that's not a problem in fact here is a similar situation ...".
An example is PG's "How not to Die" where he says:
It was really close, too. When we were visiting Yahoo to talk about being acquired, we had to interrupt everything and borrow one of their conference rooms to talk down an investor who was about to back out of a new funding round we needed to stay alive. So even in the middle of getting rich we were fighting off the grim reaper."
