I get that other people's problems don't seem real in your self-obsessed mind, but dismissing them all as "first world" only shows your own ignorance. We live in a first world nation where children go hungry, gays get lynched, black people get shot or arrested for being black, and our own government shut down because they couldn't figure out health care. Just because we have all of the money and privilege in the world as a country, doesn't mean that some of our citizens are getting shat on daily.
You know what's a truly first world problem? Indifference.
