If you focus on misery of the world you don’t have to look at your own life too critically. Bad luck happens to good people. The question is what mindset leads to better outcomes. In an unjust world is it better to focus on the injustice or is it better to keep trying to make your life better. It seems (selection bias and all) that those that have the better mindset (maybe self-centric to their own communities needs) do better regardless of income.
