Why is the experience of gratitude only accessible to a few when the world is suffering?

According to Osho, gratitude is rare because most people are unconsciously invested in unhappiness. Suffering grants blame, attention, and subtle power learned in childhood, so we cling to illness and misery even while claiming to seek joy. To taste gratitude, one must drop this morbid attachment, accept responsibility for inner states, and prepare for health and happiness rather than rehearsing wounds.
