yee's not wrong -- the industry *does* profit at the expense of children. it profits by selling games to kids that are arguably too young to be playing them and thus could potentially be subject to negative mental/emotional effects. (i also believe this has little to do with the shooting in CT.) The gaming industry doesn't do this quietly, and it doesn't do it alone. it does so in tandem with parents/adults who fail to adequately address real world issues that are simulated in games with their children who play.
i don't say this to give the industry a pass, but rather to recognize that all this is situated in a culture which unabashedly glorifies violence - esp. gun violence, not just in video games, but in nearly every form of media and even American cultural values --ya know, that good ol' 2nd amendment. and that's not to mention things like how amazingly easy our society makes it to acquire one of these glorified killing tools, or how it sensationalizes mass shootings (and thus shooters), oh and how we take utter and total sh** care of our mentally ill, to put it lightly.
but yeah, video games are definitely at the root of the problem.
