It is only necessary to think of others when thinking of creating a community. How do you include the person on the street and the millionaire. There was a segment I used to listen to on the radio about the rich and poor and how they are not so different, for example a poor person might take a shower outside because they have too at the same time a rich person could have an outdoor shower near the pool or beach. We are more similar than you think and we are all trying to live until you are old. Be there for people and they will be there for you.
