I would agree with that if one lets themselves get into that mindset. And I can easily see how that can happen because not all have it as good as I do myself. I live a pretty easy carefree life, fortunately.

But.............on the other hand............... a person can also choose to see how much good there is in the world.

There is probably only a handful of percent of really evil narcissistic psychopaths in the world. Unfortunately they tend to want to be positions of power, at least some of them.

But I think 95% of the people of the world are basically decent. If a person tries to focus on the good instead of the evil I would think that would help with depression problems. There are a lot of really good people that do good things in the world. I try, though don't always live up to it, try to be one of the good ones.
