Sense of Entitlement

Why do kids today have a sense of entitlement?  Most of them think that it is all about them and the world should revolve around their wants and desires.  They think that they are owed something when they don't have a job, let alone a pot to piss in (as my dad would say).  A couple of hours ago I received news that a child, whom I mentor, is being sent to live with his father because of the disrespect that he has recently shown his mom.  I'm not sure how I should feel about this.  I am angry that he is leaving and I don't agree with her decision; however, I don't condone his disrespectful behavior either.  He's turned 14 and now he thinks that since a couple of little, nappy-headed girls are checking him out, he's the shiznit!  This is not just his issue though; this is a problem that about 80% of today's teens have. I keep trying to remember...was I like this?  I know that I had a smart mouth, but were my parents ever contemplating kicking me out?  SMH!!
