I find much of the negativity people face comes from the world system. We can try to live decent lives but unfortunately the system whether it be media, political, they are constantly trying to interfere with peoples happiness and survival abilities. Come to think of it that is why many of us left youtube to come here. Hoping a video system that is more fair and does not only promote "socially approved" videos event though they might be nasty on the eyes and mind. So many times peoples complaining and cynical views are perfectly legit. When the media tries to control freedom of expression it's bound to cause problems. So basically what I am saying is that it is impossible to have negative thoughts in a unfair and agenda driven society. When that happens the people will be negative. Just stating a true observation.
