Rich and poor

Abu Imran, On e-mail
I refer to the picture news published in the DS on 21st July, 2010. There it was said that Prof Yunus and the Japanese Prime Minister had discussed application of the concept of the social business in Japan and other countries. So far other countries are concerned, the idea may look good because the other countries like the Third World ones are poorer. Any good idea to help the poor in changing their lots for good would be a welcome proposition. But I am at a loss to understand what good it 'd bring to the Japanese people who are already rich even by European standards. Suggesting this idea to them, at least to me looks like carrying coal to New Castle, a phrase we 'd learnt in our school days. In my humble opinion, the rich need some better suggestions to be still richer and happier.
