We need to go the base (the point where we started) and carefully evaluate the whole chain of development events to see where we went wrong.
An obvious difference between true "need" and "desire" may be kept in mind. A need in our perspective is say "provision of safe and healthy food to everyone living on the face of earth". Once this true need is fully addressed in its entirety, the next phase of development could to fulfill desires of few satiated people. Both directions need consideration but I would suggest work for the need (90% of the times) and leave the rest for fulfilling desires. In reality, need of many is compromised at the cost of desires of few people. Few people own most land with agriculture and livetsock and they are the ones who have almost all needs and many desires fulfilled...........
