Do you think saying "first world problems" is arrogant?

I just saw a youtube vid where a man was complaining that burger king wasn't selling burgers today. Someone in the comment section replied with that phrase and I was thinking is this fair? We live in a supposedly more advanced society than say Mexico or Africa. Why should we ignore those problems and focus on theirs? Isn't that policing the world? Why don't we just let them live in their hell holes and try and clean up ours?
