I am actually myself seeing more and more of that "entitlement" among people of my age. I am not sure if I am just now open about it, or its just becoming more common?
What I am noticing with younger kids and teenagers is a lack of patients. With the INTERNET, I'M, texting, etc. they don't have to wait for anything anymore. Its now now now. So maybe, you can somehow bridge cheating with the thought process of instead of waiting to learn, just taking right then and there?
Also, kids are treated with kid gloves and have been for a generation now. I am very militant with my kids (Army brat here) . When they mess up, it's usually a harsh punishment. I let them know that they chose the action that chose the consequence. I make them think twice about doing something stupid again, or even for the first time. I have not spanked them, I usually make them give up something or do something physical. They know they are loved, and that their father and I are doing what we need to to ensure that they are smart, grounded, productive, active, and healthy members of society when they become adults. They know that to get something you have to work for it. Nothing is handed to them, except at Christmas and birthdays and honor roll. The rest of the time, if they want something, the first thing they do is come up to me or their dad and say, "I want ______, what do I need to do to work for it?" and we set up a plan for them to get _________. They know about dishonesty, and what it can do them as a person, and how even one little lie can haunt them for a long time.
