The Dalai Lama discusses what readers should gain from his book The Art of Happiness:
When a person is in a miserable situation, then, yes, it is difficult to develop genuine compassion toward others. That’s why I find it difficult to say to poor people, Please have compassion toward millionaires. That’s not easy. And yet even the rich have their own kind of suffering, anxiety, doubt, and fear. So in many cases, wealthy people aren’t happy! And once those with material wealth encounter small difficulties, their amount of mental suffering is sometimes bigger than it is for those who have faced such difficulties every day.
