What you focus on, grows. Plain and simple. If you put more emphasis on things you don't like, chances are quite a bit of what you don't like will somehow end up in your life, and vice-versa. This rings very true with positivity and negativity, and the general public's attitudes about the two.
As we all know, the media tends to promote a lot of negativity. It digs into the minds of impressionable people and scares them into believing that the world is more dangerous than it really is.
BUT, that is hardly a decent excuse. Just because the general public is easily swayed by the constant negative news reports does not make them completely victimized. In fact, our general public is just as bad, if not worse than the news.
As I mentioned in another rant, controversy sells. It sells because that's what people want. The general public loves a scandal, whether for entertainment, or just to have something to whine about; whether they willingly watch an offensive parody, or notice a microscopic detail about something and turn it into a huge debate. The powers that be just happen to rightfully see it as a way to create amusement for themselves.
