What a stupid comment.
You are reading and writing this on Slashdot, a website dedicated to tech exotica. It is almost by definition a place intended for those who are assured of having regular meals and healthcare checks and literacy and owning multiple computers (e.g., news for /nerds/).
Why are you surprised that "first world problems" would be discussed here?
Should we only discuss "serious" problems like how to get fresh water or to keep the local warlord from raping our daughters until the third world gets its act together? Should we completely ignore the implications of these "first world problems" until that mythical time when all the world is brought up to our level? Why bother having a site like Slashdot in that case?
A lot of people don't recognize that working to help those who are in poverty is useful and might constructively reduce suffering, while talking to those who are not impoverished and trying to make them feel bad about it is useless, childish, and changes absolutely nothing.
We've had the ability to feed, clothe, and shelter every last man, woman, and child on this planet a few times over ever since the Industrial Revolution. The fact that we haven't done so is why, if there are any advanced aliens who can travel here, they have wisely decided that we're not worth meeting.
