You know the things that money can't buy... true love, companionship, wisdom, respect, integrity, and so on. They're values. Happiness is fulfilling your heartfelt desires, being fully alive, true to yourself. But not in isolation... Loving service to our fellows connects us and life becomes meaningful and fulfilling.
When societies and governments are not at the service of all people equally, then arrogance and exploitation risk snuffing out true human development and fulfillment. Only by loving and serving others, even with the simplest of gestures, will we attain a genuine sense of happiness and hope.
