Sometimes poor wear clothes as per the available cloth and rich wear clothes as per requirement. Quite often poor starves for food and rich starves to get 'Zero-size'. Quite often poor feels the need of shelter and rich feels the need of shelter for peace. Sometimes poor cannot take care of his closed ones as got no money. And sometimes rich cannot take care of his closed ones as he is busy in competiting with others.
If one look at both angles one comes to know that rich and poor are both in need but then why still the difference is countable?
