Many adults also take for granted what they have. We live in an acquisitive, greedy society. Individualism is higher than in any previous culture and this trend has been continuing for over a century.
We are also materialistic, and our children have grown up in a media-saturated world where they have been exposed to hundreds of thousands of advertisements designed to create demand for products, which increases their demandingness.
Families have become more child-centred and in some children this makes them treat parents as servants. Adolescents tend to be more egocentric generally so there has been an increase in narcissism in this age group (the selfie generation).
