A very simple question.
Should I, as a citizen, be concerned about what's happening to the world? I know I don't feel right when I ignore society's problems as I might have my rights infringed. But, I look around some of my people who're ignorant and they seem happy. Is this constant concern beneficial, after all?
If the world becomes bad around you, and you ignore and continue to act unconcerned, it will become a concern to you someday when you now get affected. Although knowledge of something can suffocate happiness, but it is better to be conscious and know what is coming than act unconcerned and still get affected. The bliss that ignorance gives is a façade. Knowledge remains power.
