Life's not fair and nobody except for idealistic liberals who have yet to fall into a period of deep dark cynicism ever said it was. You're born to die and then your consciousness will live on for a while before being reabsorbed back into source consciousness and then recycled back into another body and you do it all over again. If you're born poor you will always resent the rich. If you're born rich the poor will always resent you and so on. Life's life.
