Let me tell you a few of the problems that my host family in ( Dakar, Senegal) Africa have had to deal with:
1. Boys
2. Asshole coworkers
3. Dinner burning
4. Football
5. Nothing good being on TV
6. Homework
7. Low battery on the phone
8. Electric bills

These problems from what many would consider a third- world country would also be considered " first- world problems" if taken out of context.Sure, my host family is relatively wealthy, and we sometimes have to deal with unique issues like power outages, water that has to be filtered, and unpaved streets, but it doesn't negate all the petty stuff that can happen.
Way too much that's said about places in Africa get taken as an absolute experience, and the small moments of indulgence are thought to be non-existent.
Let me tell you that there will be someone whining about battery life and similar petty bullshit no matter how much money a nation has. This is because people in third-world countries are people, and people will always notice petty annoyances. People who are happy for everything they have and never complain are a small, zen, minority. The rest of us complain. It's only human.
Does this mean we shouldn't care about third- world countries? He'll no! If anything, we should strive for everyone to feel at least the basest of " first-world problems". The first step, however, is creating a dialogue where pettiness and indulgence is not determined by a nation's wealth but by a person's capability of pettiness and indulgence.
