When you talk about problems like income inequality, poverty generally, famine, we tend to focus on the parts of the problem that disturb us, the very visible parts which are often not even the problem so much as the symptom. And then ideology gets involved, and there are a lot of arguments by people on every side, kind of shouting at each other, not really trying to persuade each other but just making their argument to prove how right they are. None of which is very productive.
