I don't like the negativity associated with "first world" problem. The "first world" problems are very much real. If you believe that the rest of the world will catch up eventually with the "first world", they will have these "first world" problems too. We need to solve these "first world" problems. The only argument against it suggests a darker future where there is, and will always be, a huge gap between the rich and the poor, and the poor will stagnate forever. I don't choose to believe that.
