Why do people want to hear the constant message of war, death, famine and plague? As opposed to good news.
Or does bad news rely on people's insecurities, or do people take a vengeful delight that the bad stuff isn't happening to them.
Think about it, newspapers these days have a depressing, almost suicidal tone.
Why? Because it increases the sense of hopelessness and misery.
And how can all that be made better? By buying the products that are advertised.
You're less likely to buy stuff if you are a happy, content individual...
