Recklessness and Self-Regulation

Why do most Mainstream Media channels use recklessness as a promotional tool in juvenile programming?

Perhaps it is too easy to see this programing in malevolent light, and to see it as serving the need to prime the customers for alcohol and tobacco markets and drug use/prison industry.
On the other hand it could also act as a filter and point for self-reflection that is bound to follow at some point for most people. A spree of juvenile recklessness and rioting may form the basis for a practice of self-regulation, to build the character in positive light and avoid the tragedy of downward spiral in life.
The shakers for example have such a time reserved for every young man's start for adult life.
So even if for some time life became dysfunctional; that could paradoxically turn out to make life functional again.
