The vastness and equality of Buddhism, its comprehensiveness and thoroughness, are the most useful. The prescription it proposes is: everyone should calm down and think carefully. Happiness does not lie in the external world, but in one's own heart. Only through careful consideration, less desire and contentment, self-sacrifice for others, can one be happy and all kinds of distress will disappear.
