I don't understand why we should accept and go by such research those are done by some people in the western world, where there is no family bondage, sentiments, culture etc. As far as Indian traditional culture and way of living is concerned, even if we are poor, we give value to family, relationship, living together etc. the basic foundation to happy living is peace of mind and contentment which is inculcated from within and cannot be compared with financial purchasing power. There are enough millionaires who have amassed wealth but living in pathetic mind conditions. what about the lives of our highly profiled bollywood personalities lives etc. Money can only give materialistic comfort and not mental happiness.
