Harnessing Negative emotions!

A look at the news, and all you could possibly boil it down to, is that there's a big business for negative emotions. It was when in my teenage, when I came across my first Archies Gallery, and later on the many other card and gift shops that I realized how big and good the business of emotions was.. but those were meant to be of love, caring, missing and all that stuff... But as I grew up looking at the strikes, the reasons of various strikes, riots, curfews. The latest killings, hate mails, hate websites, communities of hate, political manifestos, even governmental actions, and the very business of media many-a-times... Excellent way of making business by harnessing negative emotions of people!!!
