Without a doubt teens need to be educated about it, however are they willing to listen? After all we must remember that many teens today believe themselves to be more wise than other teens on the past and even wiser than most people in general, and when you believe yourself to be above others, it is unlikely those teens will hear their advice, so it is a very complicated topic as there is not really an easy way to solve this problem.
And who makes teens become like that? Their parents and you can't change my mind about this. Children aren't born with thoughts, arrogance, and attitudes; they have them after they are brought up, and the elders' upbringing towards these teens plays a big role in making them the way they are today.
If parents teach their children the ways and behaviors that can make them good when they grow up, they won't suffer from these things after their children become grown, so parents need to take care of these things, the upbringing should be done in a good way for children to be good and obedient when they grow up.
If my child isn't obedient, is disrespectful with everyone including me, does what isn't good for him/her, then it's all my fault because I didn't do my best as a parent.
