You are conflating two completely separate issues. The amount of time you spend with your child has absolutely nothing to do with whether or not your child is spoiled, undisciplined, pampered, sheltered, etc.

Bad parenting (for lack of a better phase) is what causes these issues, not spending time with your child.

You are trying to make a connection between the two ideas, but I you are just recklessly generalizing your own personal observations of bad parenting.

As a counter example, I spend as much time with my daughter as I can (which is really only a 2-3 hours a day during the week due to work schedule and bed time) and she is absolutely respectful, not spoiled, and has plenty of friends.

I'm sure I'm biased regarding my own daughter; you'll just have to take my word for it.
